What is the solution of 3 sqrt x+8=-4?

ryzh [129]

Answer:

$x=-72$

Step-by-step explanation:

The given equation is $\sqrt[3]{x+8}=-4$ .

We cube both sides of this equation to obtain;

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

This implies that;

$(x+8)=-64$

We group similar terms to obtain;

$x=-64-8$

We simplify the right hand side of the equation to obtain;

$x=-72$

Therefore x=-72 is the solution of the given equation.
