Answer 2

Answer:

Correct Question:

$(3 x + 4y) {}^{3}$

By using binomial theorem or by using identity (a + b)^3 we will solve it.

$= > (3x + 4y) {}^{3} \\ = (3x) {}^{3} + 3(3x) {}^{2} (4y) + 3(3x)(4y) {}^{2} + (4y) {}^{3}$

Now simply each term

$= 27x {}^{3} + 108x {}^{2} + 144xy {}^{2} + 64y {}^{3}$

Hence 27x^3 + 108x^2 + 144xy^2 + 64y^3 should be the final answer.
