4 = 2 x

To determine

To calculate: The value of x in equation, 4=2 x .

Explanation

Given information:

The equation is 4=2 x .

Formula used:

The logarithmic identity,

log a a=1

and log a b m =mlog a b

Here, a, m and b are real number.

Calculation:

Consider the equation,

4=2 x

Take the log base 2 of both sides

log 2 4=log 2 2 x

Now apply the logarithmic identity, log a b m
