Question

What is the value of log5, 125? 3 5 15 25

Answer 1

Answer:

3

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

let $log_{5}$ 125 = n , then

125 = $5^{n}$ , that is

5³ = $5^{n}$

Since the bases on both sides are equal, both 5 then equate the exponents

n = 3
