Arrange in descending order:

22 + 3, (22)3, 2 × 22, 32 × 30, 23 × 52

Let us simplify each term,

22 + 3 = 25 = 4 × 4 × 2


= 16 × 2


= 32


(22)3 = (22 × 3)


= 26


= 64


22×2 = 2 × 2 × 2


= 8


(35) / (32) = 33


= 3 × 3 × 3


= 27


32 × 30 = 9 × 1


= 9


23 × 52 = 8 × 25


= 200


So the ascending order is as follows:


200, 64, 32, 27, 9, 8
