Question 842752: Can someone please tell me if you have a negative exponent for the denominator, do you put it to the numerator and make it positive. eg ((4x^1/4z^3/2)/3z)*((9x^3/4z^-1/2)/2x^-1). I need to simplify.

if the variable with the negative exponent is in the numerator, you place it in the denominator and make the exponent positive.
if the variable with the negative exponent is in the denominator, you place it in the numerator and make the exponent positive.
example:
5x^-2 / 7y^-3 will be equal to 5y^3 / 7x^2
the coefficients do not move because they are not being raised to the negative exponent, unless the whole thing was enclosed by a parentheses.
example:
(5x)^-2 / (7y)^-3 will be equal to (7y)^3 / (5x)^2

Moving it and changing the sign is just a mnemonic, or a shortcut.
