Question

How do you simplify `sqrt(5) / sqrt(6)`?

Answer 1

`sqrt30/6`

Explanation:

It is not good maths practice to have a radical in the denominator.

We can get rid of it by "rationalising the denominator".

Recall that: `(sqrtx)^2 = sqrt(x^2) = x`

`sqrt5/sqrt6 xx sqrt6/sqrt6 " "larr sqrt6/sqrt6=1`

=`sqrt30/6`
