What is another way to write the function f(x) = 5^x. the choices are
f(x)=(625^x)1/125
f(x) = 1/125(625^x)
f(x) = (625^x)^1/4
f(x) = 1/4(6256x)

Correct answer is f(x) = (625^x)^1/4

Step-by-step explanation:

We know that

625 = 5^4

This means

f(x) = (625^x)^1/4

f(x) = (5^(4x))^1/4

But we know this is equivalent to

f(x) = (5^(4x*(1/4))) =

= 5^(x)

Correct answer is f(x) = (625^x)^1/4

the least common denominator is 40
