Question

Simplify: 4×12^2×9^3÷6^3×27×2^2​

Answer 1

Answer:

We have the following:

(i) 58 and 712

  

By cross multiplication, we get:

5 × 12 = 60 and 7 × 8 = 56

However, 60 > 56

∴  58>712

(ii) 59and1115

By cross multiplication, we get:

 5 × 15 = 75 and 9 × 11 = 99

However, 75 < 99

∴  59<1115

(iii) 1112and1516

By cross multiplication, we get:

11 × 16 = 176 and 12 × 15 = 180

However, 176 < 180

∴  1112<1516
