$(3sqrt(35))/7$

Mathematical convention is to try and 'get rid' of any roots (radicals) that are in the denominator.

Write as: $" "(3sqrt(5))/sqrt(7)$

Multiply by 1 but in the form of $1=sqrt(7)/(sqrt(7))$

$(3sqrt(5))/sqrt(7)xxsqrt(7)/sqrt(7)" "=" "(3sqrt(5)xxsqrt(7))/7$

$(3sqrt(5xx7))/7" "=" "(3sqrt(35))/7$

How would you simplify (3 sqrt(5)) div sqrt(7)(3 sqrt(5)) div sqrt(7)?
