Question

Which shows the following expression using positive exponents?


`(xy^(-6) )/(x^(-4) y^(2) )`
A.
`(x^4)/(y^2x^6y^6)`
B.
`(xx^4)/(y^2y^6)`
C.
`(x^4)/(y^2xy^6)`
D.
`(x^4y^2)/(xy^6)`

The answer is B. If anyone needs to know.

Answer 1

The negative exponents that are in the numerator pass to positive if the base is moved to the denominator, and the negative exponents that are in the denominator pass to positive if the base is moved to the numerator.

The the answer is the option B: xx^4 / y^2 y^6
