Question

Put the numbers

(i) 4, √14, 5 and

(ii) 7, √65, 8 in ascending order.

Answer 1

(i) 4, √14, 5

Squaring all the numbers we get 4², (√14)² , 5² ⇒ 16, 14, 25

∴Ascending order: 14, 16, 25

Ascending order: √14, 4, 5

(ii) 7, √65, 8

Squaring 7, √65 and 8 we get 7², (√65)², 8² ⇒ 49, 65, 64

Ascending order: 49, 64, 65

Ascending order: 7, 8, √65
