Question

log10x=2 then x=? find out​

Answer 1

Answer:

100

Step-by-step explanation:

We know that, if log₁₀y = a , then y = 10ᵃ

Here, y = x, a = 2

Hence, log₁₀x = 2 => x = 10² = 100

Answer 2

Answer:

Value of x is 100.

Step-by-step explanation:

Given,

$log_{10}(x) = 2$

Here base of log is 10.

This is a math of logarithm.

$x = {10}^{2} = 100$

So value of x is 100.

Here applied formula is

$log_{x}(y) = a \\ y = {x}^{a}$

Some other formulas of logarithm,

$log_{x}(1) = 0$

$log_{x}(0) = 1$

$log_{x}(y) = \frac{ log(x) }{ log(y) }$

$log( {x}^{y} ) = y log(x)$

$log(x) + log(y) = log(xy)$

$log(x) - log(y) = log( \frac{x}{y} )$

$log_{x}(x) = 1$
