Question

what is the value of log x​

Answer 1

Answer:

The logarithm logb(x) = y is read as log base b of x is equals to y.

Please note that the base of log number b must be greater than 0 and must not be equal to 1. And the number (x) which we are calculating log base of (b) must be a positive real number.

For example log 2 of 8 is equal to 3.

log2(8) = 3 (log base 2 of 8)

The exponential is 23 = 8

Common Values for Log Base

Log Base Log Name Notation Log Example

2 binary logarithm lb(x) log2(16) = lb(16) = 4 => 24 = 16

10 common logarithm lg(x) log10(1000) = lg(1000) = 3 => 103 = 1000

e natural logarithm ln(x) loge(8) = ln(8) = 2.0794 => e2.0794 = 8
