Answer 1

Answer:

Q34)=(i)=Here, The answer is 13.

(ii)=Here, The answer is 25.

Step-by-step explanation:

Q34.)=Here, As per our given question,

(i)=7a-4b, Where a=3 and b=2

=7×3-4×2

=21-8

=13

So, Here the answer =13.

(ii)=a^2+2ab+b^2 ,Where a=3 and b=2

As here, The identity which is used is:[a^2+2ab^+b^2=(a+b)^2]

By applying formula, we get,

=(3+2)^2

=(5)^2

=25

So, Here the answer =25.

Thank you.
