Question

I need to find the cube root of both of these equations. Thanks!

Answer 1

Answer:

3) -1

4) $-\frac{2}{3}$

Step-by-step explanation:

Taking the cube root of a number is the same as finding what number times itsef three times equals the number under the radical sign.

$\sqrt[3]{-1}$

$=-1$

Since (-1) times itself, three times equals (-1).

$\sqrt[3]{-\frac{8}{27}}$

$=-\frac{2}{3}$

Since ($-\frac{2}{3}$) times itself three times equals ($-\frac{2}{3}$).
