Arrange in ascending order:

25, 33, 23×2, (33)2, 35, 40, 23×31

Let us simplify each term,

25 = 4 × 4 × 2


= 16 × 2


= 32


33 = 3 × 3 × 3


= 27


23×2 = 2 × 2 × 2 × 2


= 16


(33)2 = 33×2


= 36


= 729


35 = 3 × 3 × 3 × 3 × 3


= 243


40 = 1


23×3 = 2 × 2 × 2 × 3


= 24


So the ascending order is as follows:


1, 16, 24, 27, 32, 243, 729
