simplify 5/√10

Answer 1

The square root of 10 divided by 2 is the correct answer.

Answer 2

B

Explanation:

Rationalize the denominator. That means you multiply √10 on both the numerator and denominator of the question.

`(5)/(√(10) ) * ( √(10) )/(√(10) )`

The result is

`(5 √(10) )/(10)`

Notice that the 5 in the numerator, partially cancels out with the 10 in the denominator.

The answer is
`( √(10) )/(2)`
