Question

I'm stuck, please help

Answer 1

Step-by-step explanation:

A).

$\frac{2}{ \sqrt{x} }$

Using the rules of indices

$\sqrt{x} = {x}^{ \frac{1}{2} }$

So we have

$\frac{2}{ {x}^{ \frac{1}{2} } }$

And also by the rules of indices

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

Applying the rules to the above expression we have the final answer as

$2 {x}^{ - \frac{1}{2} }$

B).

$\frac{3}{ {x}^{2} }$

By using the rules of indices

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

Applying the rules to the above expression

We have the final answer as

$3 {x}^{ - 2}$

Hope this helps you
