## anonymous 4 years ago Simplify the expression. (-64)^1/3

1. anonymous

it is asking for the cube root of -64

2. anonymous

Not cubed, squared.

3. anonymous

the denominator of the exponent is the root

4. anonymous

I'll just post the actual equation for you so you can see it.

5. anonymous

but you can still tell me what the cube root of -64 is??

6. anonymous

7. anonymous

that is the same as $\sqrt[3]{-64}$

8. anonymous

what number times itself 3 times is -64 y^3=-64, what is y

Hero answered your earlier post....... (-64)^1/3 = 3 root (-64) which means find a number that when multiplied by itself three times produces -64. That number is -4, therefore: 3 root(-64) = -4 because (-4)(-4)(-4) = -64

$\sqrt[3]{-64}=-4$
