Question

Complete the following equation.

(3x?y3)4-81y12

the ? is an exponent. so is the 3, the 4, and the 12

Answer 1

find the missing exponent

Answer 2

? = 0

Answer 3

(3xy^(3))^(4)-81y^(12)

Expand the exponent (4) to the expression.
3^(4)x^(4)y^(3*4)-81y^(12)

Multiply 3 by 4 to get 12.
3^(4)x^(4)y^(12)-81y^(12)

Raising a number to the 4th power is the same as multiplying the number by itself 4 times. In this case, 3 raised to the 4th power is 81.
81x^(4)y^(12)-81y^(12)
