Question

Expand this equation

Answer 1

Explanation:

First multiply 9x3

=
`27xy^4x^3y`

give the terms that dont have a exponent a 1

=
`27x^1y^4x^3y^1`

Multiply terms with the same base

`27x^(1+3) y^4x^3y^1`

Multiply terms of same base

`27x^(1+3)y^(4+1)`

Just add all the exponents

`27x^(4)y^(5)`
