Q.1.) 1,5 × 10² =2.) 2,2 × 10³ =​

1,5 × 10²

= 1,5 × 10 × 10

= 15 × 1 × 10

= 15 × 10

= 150

2,2 × 10³

= 2,2 × 10 × 10 × 10

= 22 × 1 × 10 × 10

= 22 × 10 × 10

= 22 × 100

= 2.200

no 1

1.5 times {10}^{2} \ = frac{15}{10} times 100 \ = 15 times 10 \ = 150

no 2

2.2 times {10}^{3} \ = frac{22}{10} times 1000 \ = 22 times 100 \ = 2200
