b. 6/x^-2 (just the x is to the negative 2) ------ I said this was 6^2/x, which is 36/x
c. (-3/2)^-3 --------- I said this was 81/-8, or -81/8
is this the question?d. 6xy/3x^-1y-2) (that looks weird anyway 6xy over 3 x to the negative one, y to the negative 2) ---- I was confused. I said 2x^2y^3 (2xsquaredycubed)
note: there should be no negative exponents in the denominator
e. (2x2/3x-1)^-2 -- I said this was -4x-4/-9x2 = 4x/9x^6.
Also, is x^3 times x^-3 x^0?
