### Simplifying Monomials Help (Algebra 2)

1) (4xy³)-² • (5x-³y^4)³

2) y-2  /  y^5-3y²-20

------------------------------

1) i have 2000/x^11y^6

2) i have y^4-3y^2+10

Thanks in advance.

2) It is not monomial It cannot be simplified:

Hi

1)       1/(4xy^3)^2   *  125x^-9y^12

= (125y^6)/16x^11

2)   Let us first divide (y^5-3y²-20)  by   (y-2)

The quotient will be y^4 + 2y^3 + 4y^2  +5y+10

which means that

(y-2)(y^4 + 2y^3 + 4y^2 +5y+10) = y^5-3y²-20

Therefore,

y-2  /  y^5-3y²-20

=y-2/ (y-2)(y^4 + 2y^3 + 4y^2 +5y+10)

(y-2) in the numerator and denominator gets cancelled and the answer will be

= 1/(y^4 + 2y^3 + 4y^2 +5y+10)
