How do you find the value of log 5 on a log table?

Answer: The value of log 5 is 0.6990 The easiest and fastest way to calculate the value of log 5 is with the help of a logarithmic table. = log 10 – log 2 (Since, log(A/B) = log A – log B)

What is the value of log 5 by 3?

How do you calculate log3 value?

Using a scientific calculator, we find that the value for log 3 = x is x = . 477121 (rounded to 6 decimal places); therefore, when 10 is raised to the .

What is Loga * log B?

log A + log B = log AB. This law tells us how to add two logarithms together. Adding log A and log B results in the logarithm of the product of A and B, that is log AB. For example, we can write.

How do you solve log a log B?

log(a/b) = log a -log b, a > 0, b > 0. log an = n (log a) (Logarithm of a power). logx y = logmy / logmx (Change of base rule). logx y = 1 / logy x .

What is the formula to calculate log b?

log b ( x ∙ y) = log b ( x) + log b ( y) Logarithm quotient rule. log b ( x / y) = log b ( x) – log b ( y) Logarithm power rule. log b ( x y) = y ∙ log b ( x) Logarithm base switch rule. log b ( c) = 1 / log c ( b) Logarithm base change rule. log b ( x) = log c ( x) / log c ( b)

How to write 36 in terms of log2 and log3?

To write this expression in terms of log2 and log3 you first have to write number 36 as a product of powers of 2 and 3.

What is the product of log and logarithm?

Logarithm product rule The logarithm of the multiplication of x and y is the sum of logarithm of x and logarithm of y. log b (x ∙ y) = log b (x) + log b (y)

What are the rules of base b logarithm?

Logarithm Rules. The base b logarithm of a number is the exponent that we need to raise the base in order to get the number. Logarithm definition. When b is raised to the power of y is equal x: Then the base b logarithm of x is equal to y:
