Which expression is equal to \frac{7}{ \sqrt{} 5}?

Question

Which expression is equal to
`\frac{7}{ \sqrt{} 5}`?

Answer 1

multiply both nominator and denominator by √5
(7*√5)/(√5*√5)=7√5/5

7√5/5

Answer 2

The expression equivalent to the given expression is:
`(7√(5) )/(5)`

Explanation:

We are given the expression as
`(7)/(√(5) )`

we will multiply and divide by
`√(5)` i.e. we use the method of "rationalizing a denominator"( the method used to remove a square root or a cube root from the denominator) to obtain the following expression:
`(7√(5) )/(5)`

Hence, the expression equivalent to
`(7)/(√(5) )` is
`(7√(5) )/(5)`.
