Please answer this i need help

Answer 1

You're looking for a number that gives -1000 when cubed. In other words, you're looking for the cubic root of -1000.

In fact, cubic root and cube are one the opposite of the other, meaning that

`a^3=b \iff \sqrt[3]{b}=a`

So, you have

`x^3=-1000 \iff x = \sqrt[3]{-1000} = -10`

Answer 2

x = -10
