1-82.

What value(s) of $x$ will make each equation true? Homework Help ✎

1. $\sqrt[3]{x}=-2$

• Since the cube root is the solution to $x^3$, you can just give $−2$ an exponent of $3$.

$−8$

1. $\sqrt{x}=12$

• You should be able to do this one in your head.

1. $|x+1|=4$

• Look carefully at this equation. You can solve the equation for $x$, but there is more than one possible answer.

$x=3$ or $x=−5$

Do you see why there are two answers?
