Question

How do i do this and what is the answer

Answer 1

`4x^6`

Explanation:

Let's write it as a fraction:

`(4x^3y)/(x^(-3)y)`

Division of exponents rule:
`(a^x)/(a^b)= a^(x-b)`

Use this formula for x and y

`(x^3)/(x^(-3)) = x^(3- (-3)) = x^6`

`(y^1)/(y^1) = y^(1-1) = y^0 = 1`

Now use these answers in the fraction

`4x^6*1 = 4x^6`
