Respuesta :

Multiply the coefficients (numbers out front): 9 times 9 = 9*9 = 81

Multiply the x terms by adding up the exponents: x*x^5 = x^1*x^5 = x^(1+5) = x^6

Multiply the y terms by adding up the exponents: y^2*y^2 = y^(2+2) = y^4

Now take those results we got above and write them all together to form the final answer of 81x^6y^4

Side Note: I used the rule x^a*x^b = x^(a+b)
