Question #8a190

Answer 1

`2^6x^10y^16`

Explanation:

Start by getting rid of the brackets, which is done by distributing the powers to each of the elements inside.
`(-2xy^2)^4(2x^3y^4)^2=(-2)^4x^4y^8*2^2x^6y^8`

Now group all the similar items, remembering that a negative number raised to an even power becomes positive, and that the powers of like items should be added together.

`=2^6x^10y^16`
