Step-by-step explanation: To begin, negative exponents denote reciprocal. To remove the negative exponent, you "flip it" to 1/x. The first part (q 1 r 1 s 6) would be replaced by ((1/q) * (1/r) * (1/s 6)). Simplifying, we get (1 / (qrs 6)). In the same way as the second parth (r 3 sq 5): ((1/r3) * s * (1/q 5)).
