Question

8x^-9+(-3x^-3y-2)(5/x^6y-2)

Answer 1

`8x^(-9)+(-3x^(-3)y^(-2))((5)/(x^6y^(-2)))`

the first step is to deal with the negative exponents, which causes numbers to go to the other side of the fraction

8x^{-9}+(-3x^{-3}y^{-2})(\frac{5}{x^6y^{-2}})

goes to

`(8)/(x^9)+((-3)/(x^3y^2))((5y^2)/(x^6))`

now we can simplify the multiplied terms

`(8)/(x^9)+((-15)/(x^9))`

Now that we have common bases, we can add the 2 fractions together to get

`(-7)/(x^9)`
