1) (3^7 • 11^7)/33^6 = (3^7 • 11^7)/(3^6 • 11^6) = 3 • 11 = 33
2) 28^6/(7^5 • 4^5) = (4^6 • 7^6)/(7^5 • 4^5) = 4 • 7 = 28
3) (5^8 • 9^5)/45^5 = (5^8 • 9^5)/(5^5 • 9^5) = 5^3 = 125
4) (3^16 • 2^10)/54^5 = (3^16 • 2^10)/(18^5 • 3^5) = (3^16 • 2^10)/(6^5 • 3^10) = (3^16 • 2^10)/(2^5 • 3^15) = 3 • 2^5 = 3 • 32 = 96
5) 36^5/(2^9 • 3^8) = (9^5 • 4^5)/(2^9 • 3^8) = (3^10 • 2^10)/(2^9 • 3^8) = 3^2 • 2 = 9 • 2 = 18
6) 18^4/12^5 = (6^4 • 3^4)/(3^5 • 4^5) = (2^4 • 3^8)/(3^5 • 2^10) = 2^-6 • 3^3 = 27/64
