Question

How do you simplify `2x^3y^-3*2x^-1y^3` and write it using only positive exponents?

Answer 1

`(2x^3y^3)/(2xy^3)`

Explanation:

anything to a negative exponent means it's really `1/"number"`
therefore:
`(2x^3)/y^3*y^3/(2x)`

Fractions multiply top`times`top, bottom`times`bottom

`(2x^3*y^3)/(2x*y^3)`
