उत्तर
We know that rationalization factor for `3sqrt2 +2sqrt3` and `sqrt3-sqrt2`are `3sqrt2 - 2sqrt3`and `sqrt3 +sqrt2`respectively. We will multiply numerator and denominator of the given expression `(3sqrt2 -2sqrt3)/ (3sqrt2 +2sqrt3)` and `sqrt12/(sqrt3-sqrt2)`by `3sqrt2-2sqrt3`and `sqrt3 +sqrt2`respectively, to get
`(3sqrt2 -2sqrt3)/ (3sqrt2 +2sqrt3) xx (3sqrt2 -2sqrt3)/ (3sqrt2 -2sqrt3) +sqrt12/(sqrt3-sqrt2) xx (sqrt3 +sqrt2)/(sqrt3 +sqrt2) =((3sqrt2)^2+(2sqrt3)^2 - 2xx 3 sqrt2 xx 2sqrt3)/((3sqrt2)^2 -( 2sqrt3)^2 ) +(sqrt36+sqrt24)/((sqrt3)^2-(sqrt2)^2)`
`= (18+12-12sqrt6)/(18-12) +(6+sqrt24)/(3-2)`
`= (30-12sqrt6 +36 +12sqrt6)/6`
`=66/6`
`=11`
