Okay maybe I am stupid, but I got quantity A is larger. I did it by converting them all to improper fractions and decimals. Both times I got 91.875. The correct answer is they are equal. Can someone show me how I’m wrong because video has no explanation

Quantity A: 2^{6/4} X 3 ^{1/2} X 6 ^{3/2} (The X means times)

Quantity B: 72
