Answer 1

\[\LARGE (2x+5)^2(2x+5)^2(2x+5)\]

start expanding... (I'd choose this "UGLY" process...)

Answer 2

but i dont want use this i think we should use choose

Answer 3

You can validate it through the binomial theorem which is relatively easy once you get the grasp of it.

Answer 4

hmm what math u all r in

Answer 5

you cam use the binomial expansion for positive integers

(a + b)^n = a^n + nC1 a^(n-1) b x + nC2 a^(n-2) b^2 x^2+.......... + b^n
