(a + b)^2 = a^2 + 2 a b + b^2
= 20 +2*6*√35 + 63
= 83 + 12 √35

If you are in a big hurry, it would be wise to as somebody younger. I have not looked at that subject since the Korean war.
however to show that:
√5 √7 = √35
say
a^.5 * b^.5
take log
.5 log a + .5 log b
= .5 log (a+b)
= log (a+b)^.5
antilog
(a b)^.5

TYPO
.5 log a + .5 log b
= .5 log (ab)
= log (ab)^.5
antilog
(a b)^.5
