Rationalise the denominator of each of the following
(i)`3/(sqrt(5))`
(ii) `3/(2sqrt(5))`

Text Solution

Verified by Experts

(1)`3/(sqrt(5))`
=`[3 xx (sqrt(5)] / [(sqrt(5)) xx (sqrt(5)]`
=`(3 xx sqrt(5)/5`
.Hence, rationalized.
(2)`3/(2 sqrt(5))`
=`[3*( 2sqrt(5)]/[(2 sqrt(5))xx(2 sqrt(5)]`
=`[(6 xx sqrt(5)]/20`
.Hence, rationalized.
