Multiply the monomials showing and explaining each step in d

Multiply the monomials, showing and explaining each step in detail. (9x³y⁵)(-7x⁴y)

Solution

(9x3y5)(-7x4y)

multiplying constant separately, x terms together and y terms together:

= (9*-7)(x^3*x)(y^5*y) ------> ( x^3*x = x^(3+1) ) ; ( y^5*y = y^(5+1) )

= -63(x^4)(y^6)

= -63x^4y^6
