When people ask, "What is the value of log?", they typically refer to base 10 logarithms.
Let’s apprehend it step-by-step:
log₁₀(1) = 0 → because 100= 1000 = 1100=1
log₁₀(10) = 1 → because a hundred and one=10101 = 10101=10
log₁₀(a hundred) = 2 → because 102=100102 = 100102=100
The Value of logs relies on matters:
The base (maximum generally 10 or e),
The quantity you're taking the log of.
Knowing the basic log values is crucial for fixing exponential and logarithmic problems effectively.
Logarithms are a mathematical concept that represent the opposite of exponentiation. In simple terms, a logarithm tells us the power to which a base must be raised to produce a given number. For example, since 10^3 = 1000, it means log₁₀(1000) = 3. The general form is written as logₑ(x) = y, which means b^y = x. The most common types are the common logarithm (base 10) and the natural logarithm (base e). Logarithms are useful for simplifying large calculations, solving exponential equations, and are widely used in science, engineering, computer science, and finance.
This is a trendy reference desk of the value of log (base 10) from numbers 1 to 10. Memorising information that can simplify complicated math issues.

Many People ask, How to calculate log value manually? The top information is that there’s a technique:
Steps:
Break the number into recognised values or use the log of legal guidelines:
log(ab) = log a + log b
Log (a/b) = log a − log b
log(aⁿ) = n × log a
Example:
“So, when learning to calculate log cost, remember the logarithmic laws. They help make simplification easier.”
Not everybody makes use of log tables anymore, so here’s the way to find the cost of the log of the usage of a scientific calculator:
Press the LOG key.
Type the wide variety (e.g., 7).
Press = Enter.
Your solution (e.g., log(7) = 0.8451) is displayed.
This is the quickest manner in case you're looking to discover the value of log for any range. Knowing the way to locate the cost of logging the use of tech equipment is a contemporary math skill.
Understanding log properties helps you simplify and calculate the log price quickly. These are in particular useful for huge numbers or algebraic expressions.
Key Logarithmic Rules:
logₐ(1) =0
logₐ(a) = 1
log(ab) = log a + log b
Log (a/b) = log a − log b
log(aⁿ) = n log a
Change of Base Formula:
Mastering those allows you to understand how to calculate the log cost for unfamiliar numbers.
There are numerous myths about logarithms that lead to confusion among People. Let’s explore and clarify them separately:
1 .Myth: log(1) = 1
Fact: log(1) = 0
Many students think that the log of 1 is 1; however, that’s incorrect. In reality, any quantity raised to the power of 0 equals 1, so the logarithm of 1 (in any base) is always zero.
2. Myth: log(ab) = log a × log b
Fact: log(ab) = log a + log b
This mistake comes from complicated logarithmic policies with algebraic multiplication. Logarithms flip multiplication into addition, making calculations less difficult. So, multiplying inside the log will become including outside.
3. Myth: You can locate the log of poor numbers
Fact: Logarithms of bad numbers are undefined in real numbers
Logarithms can only be taken for super numbers in real math. Since no actual strength of a wonderful range gives a poor result, the log of a poor quantity is undefined unless you are operating in complex numbers.
4. Myth: Logarithms are outdated
Fact: Logs are widely used in computing, device getting to know, and data
Some consider logs are handiest from antique math textbooks, however, that’s a long way from true. Logarithmic functions are vital in current programs like fact technology, AI models, algorithm complexity, and exponential statistics analysis.
Let’s apply what you’ve discovered in real examples:
Step 1: 100 = 10210^2102
Step 2: log(100) = log(10210^2102) = 2·log(10) = 2·1
Final answer: log(100) = 2
Step 1: Write 5 as 10/2 → log(5) = log(10/2)
Step 2: Use quotient rule → log(10/2) = log(10) − log(2)
Step 3: log(10) = 1 and log(2) ≈ 0.301030
Step 4: 1 − 0.301030 = 0.698970
Final answer: log(5) ≈ 0.698970
Step 1: 9 = 323^232
Step 2: log(9) = log(323^232) = 2·log(3)
Step 3: log(3) ≈ 0.477121 → 2 × 0.477121 = 0.954243
Final answer: log(9) ≈ 0.954243
Step 1: 8 = 232^323
Step 2: log(8) = log(232^323) = 3·log(2)
Step 3: log(2) ≈ 0.301030 → 3 × 0.301030 = 0.903090
Final answer: log(8) ≈ 0.903090
Method A (product rule): log(2×5) = log(2) + log(5) = 0.301030 + 0.698970 = 1.000000
Method B (recognize product): 2×5 = 10 → log(10) = 1
Final answer: log(2×5) = 1
Logarithms may seem intimidating at the beginning; however, after you recognise the value of log 1 to 10, they become a lot less complicated to comprehend. From fixing simple math troubles to deciphering complex actual-global information, logarithms play an important role in many areas of getting to know and era. The price of a log allows us to make sense of exponential relationships, which are common in subjects like technology, engineering, and finance. By knowing the value of log for numbers 1 to 10, you build a solid basis for operating with logarithmic expressions. Learning how to calculate log value, the use of formulas and shortcuts permits you to simplify tough troubles. Practising how to discover the cost of a log with tables and calculators improves each pace and accuracy. With consistent practice and focus on their actual-life applications, logarithms can end up considered one of your maximum powerful and reliable mathematical tools.
Answer: The price of log (base 10) depends on the wide variety; as an example, log(10) = 1 and log(1) = 0.
Answer: Log(10) = 1 in base 10, which means 10 raised to the power 1 equals 10.
Answer: Use a calculator or log desk, or follow log regulations like log(ab) = log a + log b.
Answer: Logarithms are expressed as “log base (b) of number (x),” written as log₍b₎(x).
