Question

Select all of the expressions equivalent to c6d6
.
(cd−1)6
c12d18c2d3
c8d3c2d9
c6d−6
c−6d6
(c−1d)−6

Answer 1

None of them. Simplifying each:

- (c d^{-1})^6 = c^6 d^{-6}
- c^{12} d^{18} c^2 d^3 = c^{14} d^{21}
- c^8 d^3 c^2 d^9 = c^{10} d^{12}
- c^6 d^{-6} = c^6 / d^6
- c^{-6} d^6 = d^6 / c^6
- (c^{-1} d)^{-6} = c^6 d^{-6}

None simplify to c^6 d^6.
