Please help me on this

Answer 1

Simplify the radical by breaking the radicand up into a product of known factors.
Your answer is A. -0.5

Answer 2

For this case, we have that by definition:

$(-0.5) ^ 3 = -0.125$

Then we can rewrite the given expression as:

$\sqrt [3] {(- 0.5) ^ 3}$

For properties of roots we have that:

$\sqrt [n] {(a) ^ n} = a$

So:

$\sqrt [3] {(- 0.5) ^ 3} = - 0.5$

So, we have to:

$\sqrt [3] {- 0.125} = - 0.5$
