After rationalizing the denominator of (...

After rationalizing the denominator of `(7)/(3sqrt(3) - 2sqrt(2))`, we get the denominator as

A

`13`

B

`19`

C

`5`

D

`35`

Text Solution

Verified by Experts

The correct Answer is:
B
`(7)/(3sqrt(3) - 2sqrt(2)) = (7)/(3sqrt(3) - 2sqrt(2)). (3sqrt(3) - 2sqrt(2))/(3sqrt(3) + 2sqrt(2))`
[multiplying numerator and denominator by `3sqrt(3) + 2sqrt(2)`]
`= (7(sqrt(3) + 2sqrt(2)))/((3//sqrt(3))^(2) - (2sqrt(2))^(2))`
