Question

8 power of x = 2 x = ?

Help please

Answer 1

The value of x is 1/3 .

Explanation:

You have to use Logarithm Law,

`log_(a)(b) = x = > {a}^(x) = b`

So you have to substitue the following values into the formula :

Let a = 8,

Let b = 2,

Let x = x,

`{8}^(x) = 2 = > log_(8)(2) = x`

`x = log_(8)(2)`

`x = (1)/(3)`

Answer 2

2√2

Explanation:

√8 = √2³ = √2²×2 = 2√2
