Solution:
(i) 57.36 = 5.736 x 10¹
(ii) 3500000 = 3.5 x 10⁶
(iii) 273000 = 2.73 x 10⁵
(iv) 168000000 = 1.68 x 10⁸
(v) 4630000000000 = 4.63 x 10¹²
(vi) 345 x 10⁵ = 3.45 x 10² x 10⁵ = 3.45 x 10⁷

Question 2.
Solution:
(i) 3.74 x 10⁵
= \(\\ \frac { 374 }{ 100 } \) x 10⁵

Question 3.
Solution:
(i) Height of Mount Everest = 8848 m
= 8.848 x 1000
= 8.848 x 10³
(ii) Speed of light = 300000000 m/sec.
= 3.00000000 x 100000000
= (3 x 10⁸) m/sec.
(iii) Distance between the earth and the sun = 149600000000 m
= (1.49600000000 x 100000000000)m = (1.496 x 10¹¹) m

Question 4.
Solution:
Mass of earth = (15.97 x 10²⁴) kg
and mass of moon = (7.35 x 10²²) kg
= Total mass of earth and moon

Question 5.
Solution:
(i) 0.0006
= \(\\ \frac { 6 }{ 10000 } \) = \(\frac { 6 }{ { 10 }^{ 4 } }\) = 6.10^-4
