-8x^4y^3 × -6xy^-7

Take out the constants

-(8 × -6)x^4xy^3y^-7

Simplify 8 × -6 to -48

-(-48)x^4xy^3y^-7

Regroup terms

-(-48x^4xy^3y^-7)

Use the Product Rule: x^a x^b = x^a + b

-(-48x^4 += 1y^3 - 7)

Simplify 4 + 1 to 5

-(-48x^5y^3 - 7)

Simplify 3 - 7 to -4

-(-48x^5y^-4)

Use Negative Power Rule: x^-a = 1/x^a

-(-48x^5 × 1/y^4)

Simplify 48x^5 × 1/y^4 to 48x^5/y^4
