Question

Connor is evaluating some expressions. Help him to find the value of x.

$5^x$ = 625

• A. 3
• B. 5
• C. 2
• D. 4

Answer 1

The correct option is D 4

Let us substitute x = 3 in the given expression.
$5^3$ = 5 $\times$ 5 $\times$ 5 = 125
This does not satisfy the given expression.


Let us substitute x = 5 in the given expression.
$5^5$ = 5 $\times$ 5 $\times$ 5 $\times$ 5 $\times$ 5 = 3,125
This does not satisfy the given expression.


Let us substitute x = 2 in the given expression.
$5^2$ = 5 $\times$ 5 = 25
This does not satisfy the given expression.


Let us substitute x = 4 in the given expression.
$5^4$ = 5 $\times$ 5 $\times$ 5 $\times$ 5 = 625
This satisfies the given expression.

Hence, the value of x = 4.
