the answer is simply 18 by applying identity (a+b)^2=a^2+b^2+2ab
Anonymous:
apply identity
approx. 18
The answer is 3^2 * 2 = 18.
explain it??
(root 2 + 2 root 2)^2
= (3 root )^2
= 3^2 * 2
= 18.
= (3 root )^2
= 3^2 * 2
= 18.
Sorry..In 2nd step it should be (3 root 2)^2
apply identity,(√2)^2+(√8)^2+2(√2)(√8)
which gives 2+8+8
=18 :)
