Question

1(a+4b)^3
2(5+4ab)^3
​

Answer 1

Answer:

2+16 = 18 is answer

5+24=29 is the answer

Answer 2

First we should know the identity to solve this so….
(x+y)^3 = x^3 + y^3 +3xy(x+y )

So for both the parts we have to use the same identity


We can look


Solution( step by step)=

1) a^3 + 64b^3 + 12ab( a+4b) = a^3+ 64b^3+ 12a^2b + 48ab^2

2) 125+64a^3b^3+ 60ab(5+4ab) = 125+64a^3b^3+ 300ab+240a^2b^2
