Question

I'm stuck, please help

Answer 1

Explanation:

A).

`(2)/( √(x) )`

Using the rules of indices

`√(x) = {x}^{ (1)/(2) }`

So we have

`\frac{2}{ {x}^{ (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}^{ - (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
