What is the solution of RootIndex 3 StartRoot x + 8 EndRoot = negative 4?

erica [24]

Answer: First option.

Step-by-step explanation:

Given the following equation provided in the exercise:

$\sqrt[3]{x+8}=-4$

You can follow the steps indicated below in order to find the solution of this equation:

1. Cubing both sides of the equation, you get:

$(\sqrt[3]{x+8})^3=(-4)^3\\\\x+8=-64$

2. Finally you must subtract 8 from both sides of the equation:

$x+8-8=-64-8\\\\x=-72$

You can notice that this solution matches with the first option.
