The approximate value

Question

The approximate value of `(3sqrt(12))/(2sqrt(28))` `-:` `(2sqrt(21))/(sqrt(98))` is :

Options:

A . 1.0605

B . 1.0727

C . 1.6007

D . 1.6026

Answer: Option A

`(3sqrt(12))/(2sqrt(28))` `-:` `(2sqrt(21))/(sqrt(98))` =`(3sqrt(12))/(2sqrt(28))` x `(sqrt(98))/(2sqrt(21))`

=`(3sqrt(4 xx 3))/(2sqrt(4 xx 7))` x` (sqrt(49 xx 2))/(2sqrt(21))` = `(6sqrt(3))/(4sqrt(7))` x `(7sqrt(2))/(2sqrt(21))`

= `(21sqrt(6))/(4sqrt(7 xx 21))` = `(21sqrt(6))/(28sqrt(3))` = `3/4`` sqrt(2)`= `3/4` x 1.414 = 3 x 0.3525 = 1.0605
