Answer 1

Answer:

50

Step-by-step explanation:

It ain't that hard. You just have to be careful and take things slow.... Here's how we can work it out:

$\frac{ {8}^{ \frac{1}{3} } }{ {5}^{ - 2} } = \frac{ \sqrt[3]{ {8}^{1} } }{ \frac{1}{ {5}^{2} } } = \frac{ \sqrt[3]{ {2}^{3} } }{ \frac{1}{ {5}^{2} } } = \frac{2}{ \frac{1}{25} } = 2 \times 25 = 50$

I've used a couple things.

${8}^{ \frac{a}{b} } = \sqrt[b]{ {8}^{a} }$

${5}^{ - a} = \frac{1}{ {5}^{a} }$

and...

$\frac{ \frac{a}{b} }{ \frac{c}{d} } = \frac{ad}{bc}$

In other words,

$\frac{2}{ \frac{1}{25} } = \frac{ \frac{2}{1} }{ \frac{1}{25} } = \frac{2 \times 25}{1 \times 1} = 2 \times 25 = 50$

Hope I've helped ;)
