Hope you are able to understand the solution. :-D
Pretty sure the answer is A
Answer:
16x^2 -48xy^3 +36y^6
Step-by-step explanation:
(4x-6y^(3))^(2)
FOIL
(4x-6y^3) (4x - 6y^3)
first: 4x*4x = 16x^2
outer : 4x (-6y^3) =-24xy^3
inner : 4x (-6y^3) =-24xy^3
last: -6y^3 * - 6y^3 = 36y^6
Add them together
16x^2 -24xy^3-24xy^3+36y^6
Combine like terms
16x^2 -48xy^3 +36y^6
Answer:

Step-by-step explanation:

Factorize

The function is not invertible if you think of it as

because it is not injective: 
So, if we restrict the domain to the positive numbers only:

Note that the range is actually
, so we can be more precise and write

To find the inverse, we solve the expression for x:

But since we restricted to positive values of x, the inverse is
