Question

Find the real solution(s) of the equation. Round your answer to two decimal places

when appropriate.
(x + 4) = -125

Answer 1

-9

Explanation:

Given the expression

(x+4)³ = -125

We are to find the value of x

Cube root both sides

³√(x+4)³ = ³√-125

x+4 = -5

Subtract 4 from both sides

x+4-4 = -5-4

x = -9

Hence the real solution to the equation is -9
