Question

if log2 x=3,then x will be equal to​

Answer 1

The value of x = 8

Correct question : If $\displaystyle \sf log_{2}x = 3$ then x will be equal to

Given :

$\displaystyle \sf log_{2}x = 3$

To find :

The value of x

Formula :

$\displaystyle \sf log_{a}x = n \: \: gives \: \: x = {a}^{n}$

Solution :

Step 1 of 2 :

Write down the given expression

Here the given expression is

$\displaystyle \sf log_{2}x = 3$

Step 2 of 2 :

Find the value of x

$\displaystyle \sf log_{2}x = 3$

We know that ,

$\displaystyle \sf log_{a}x = n \: \: gives \: \: x = {a}^{n}$

Thus we get

$\displaystyle \sf x = {2}^{3}$

$\displaystyle \sf{ \implies }x = 8$

Hence the required value of x = 8
