Question

Simplify the following:

`3sqrt(3) + 2sqrt(27) + 7/sqrt(3)`

Simplify

Solution

`3sqrt(3) + 2sqrt(27) + 7/sqrt(3) = 3sqrt(3) + 2sqrt(3 xx 3 xx 3) + 7/sqrt(3) xx sqrt(3)/sqrt(3)`

= `3sqrt(3) + 6sqrt(3) + (7sqrt(3))/3`

= `9sqrt(3) + (7sqrt(3))/3`

= `(27sqrt(3) + 7sqrt(3))/3`

= `(34sqrt(3))/3`
