Thanks so much in advance!
2. (1.2)^5(1.2)^-2
3. r^3t^-7 / t^5
Thanks so much in advance!

1. (-3q^-1)^3 =( -3/q)^3 = -27/q^3
(-27/q^3)(q^2) cross multiplication
-27/q
2. (1.2^5 / 1) (1/1.2^2)
1.2^5 / 1.2^2 = 1.2^3 = 1.728
3. (r^3)(1/t^7) / t^5
r^3/t^7 / t^5
(r^3 / t^7) (1/t^5)
r^3 / t^12
(-27/q^3)(q^2) cross multiplication
-27/q
2. (1.2^5 / 1) (1/1.2^2)
1.2^5 / 1.2^2 = 1.2^3 = 1.728
3. (r^3)(1/t^7) / t^5
r^3/t^7 / t^5
(r^3 / t^7) (1/t^5)
r^3 / t^12
