Can anyone me with letter c in this question? i can’t get it right

-5/6

Step-by-step explanation:

(25/4)^(3x) = 32/3125

Rewrite as powers of 2 and 5:

(5²/2²)^(3x) = 2⁵/5⁵

Rewrite the left side as the inverse:

(2²/5²)^(-3x) = 2⁵/5⁵

Solve for the exponent:

-3x = 5/2

Solve for x:

x = -5/6

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
