What is the value of log625^5? a: -4 b: -1/4 c: 1/4 d: 4

The value of is

Step-by-step explanation:

We want to evaluate .

The base of this logarithm is and the number is .

We need to express the number as the base raised to a certain index.

This implies that,

Recall now that,

.

We apply this property to obtain,

Recall again that,

.This implies that,

The correct answer is C.
