Question

Assuming that x, y, z are positive real numbers, simplify the following:

`(sqrt(x^-3))^5`

Answer in Brief

Solution

We have to simplify the following, assuming that x, y, z are positive real numbers

Given `(sqrt(x^-3))^5`

As x is positive real number then we have

`(sqrt(x^-3))^5=(sqrt(1/x^3))^5`

`=(sqrt1/sqrt(x^3))^5`

`=(1/x^(3xx1/2))^5`

`=(1/x^(3/2))`

`(sqrt(x^-3))^5=(1^5/x^(3/2xx5))`

`=1/x^(15/2)`

Hence the simplified value of `(sqrt(x^-3))^5` is `1/x^(15/2)`
