(ii) (-1)501 × [(27)4 ÷ (9)5]
(iii) ..(3.12.)3……………..

(i) (-3)3 × 52

= (−3) × (−3) × (−3) × 5 × 5
= −27 × 25
= −675

#### Question 5. Write the prime factorisation of the following numbers in the exponential form:

(i) 24000
(ii) 12600
(iii) 14157

(i) 24000

= 2 × 2 × 2 × 2 × 2 × 2 × 3 × 5 × 5 × 5
= 26 × 31 × 53

(ii) 12600

= 2 × 2 × 2 × 3 × 3 × 5 × 5 × 7
= 23 × 32 × 52 × 71

(iii) 14157

= 3 × 3 × 11 × 11 × 13
= 32 × 112 × 131

#### Question 6. Express the numbers appearing in the following statements in scientific notation:

(i) The earth has 1,353,000,000 cubic km of water.
(ii) The population of India was about 1,027,000,000 in march, 2001.
(iii) 60,230,000,000,000,000,000,000 molecules are contained in a drop of water.

(i) The earth has 1,353,000,000 cubic km of water.

= 1.353 × 109 cubic km

(ii) The population of India was about 1,027,000,000 in march, 2001.

= 1.027 × 109

(iii) 60,230,000,000,000,000,000 molecules are contained in a drop of water.

6.023 × 1022 molecules

#### Question -7. Compare the following numbers:

(i) 5.976 × 1024; 8.689 × 1023
(ii) 3.7662 × 1017; 3.7671 × 1017

(i) 5.976 × 1024; 8.689 × 1023

Here in 5.976 × 1024, 102 is greater than in 8.689  × 1023

5.976 × 1024 > 8.689 × 1024
(ii) 3.7662 × 1017  >3.7671 × 1017

Here 1024 is multiplied in both and 76671 > 7662
3.76671 × 1017 > 3.7662 × 1017
