Step-by-step explanation:

You can't do anything in the parenthesis because there is no like terms so you go on to multiplication.

You multiply 2x^5 and 3x^3

When you multiply numbers with exponents you add the exponents and multiply the numbers so you should end up with 6x^8

After that you multiply the y's

Every number at least has an exponent to the first so the y with out an exponent has an invisible one that's to the first power

So when multiplying the y's you add the 3 and the invisible exponent which should then equal y^4

Your final product will end up being 6x^8y^4
