Log Calculator (Logarithm)
Base 10 is commonly used in science and engineering, base e in math and physics, and base 2 in computer science. When the argument of a logarithm is the product of two numerals, the logarithm can be re-written as the addition of the logarithm of each of the numerals. logb(x × y) = logbx + ...
What is log base 10?
Log base 10, also known as the common logarithm or decadic logarithm, is the logarithm with base 10. It answers the question: 'To what power must 10 be raised to get a given number?' For example, log base 10 of 100 equals 2 because 10 raised to the power of 2 equals 100. It is commonly written as log(x), lg(x), or log10(x).

How do you calculate log base 10?
To calculate log base 10 of a number x, find the exponent y such that 10^y = x. For perfect powers of 10 (like 10, 100, 1000), the answer is simply the exponent (1, 2, 3). For other numbers, use a calculator or the change of base formula: log10(x) = ln(x) / ln(10). Our calculator provides instant results with step-by-step explanations.

What is the domain of log base 10?
The domain of log base 10 is all positive real numbers (x > 0). Logarithms are undefined for zero and negative numbers. This is because no power of 10 (a positive base) can produce zero or a negative result. The range of log base 10 is all real numbers, from negative infinity to positive infinity.

Say I want to Find Log(10)1.5, I know that Log1=0 and Log2=0.3010, how can I use this relation to find the log of 1.5 with base 10?
Top answer 1 of 9

I'm not sure what you are looking for here. Knowing log 1 =0 and log 2 = 0.3010 doesn't immediately give you a way to calculate log 1.5. (unless perhaps you want to explore doing something with power series of the natural log). By definition, if log 1.5 = x, then 1.5 = 10x . If you didn't have access to a calculator that produces logs, then you can do a numerical search: 100.1 = 1.259, 100.2 = 1.585, so x must be a little less that 0.2...

Just like subtraction is the inverse of addition and division is the inverse of multiplication, logarithmic functions are the inverse of exponential functions - i.e. logarithms are the mathematical process of "undoing" exponentiation, or raising a number to another number power. If you google logarithm rules, you'll find that values multiplied/divided inside the logarithm can be "split" by addition and subtraction of logarithms. For your example, you have log10(1.5) which can also be written log10(3/2). This can be rewritten as log10(3)-log10(2). From the log table, you can fill in that this is equal to 0.4771-0.3010=0.1761.
