Answer 2

Step-by-step explanation:

There are several ways to solve this, and here are the examples:

1.

one way to solve this is knowing the formula (a+b)^3:

a^3 + 3a^3*b + 3ab^2 + b^3

[if you had (x + y)^3, just pretend a = x and b = y]

here you have x^3 and 64 = 4^3 => a = 4x

27 = 3^3

it seems this might be the case of (4x + 3)^3

You can check it by plugging 4x and 3 into the formula. If you get your initial problem, you got the solution. (Btw, you do get your initial expression!).
