**Question 1.**

**Solution:**

(i) 57.36 = 5.736 x 10^{1}

(ii) 3500000 = 3.5 x 10^{6}

(iii) 273000 = 2.73 x 10^{5}

(iv) 168000000 = 1.68 x 10^{8}

(v) 4630000000000 = 4.63 x 10^{12}

(vi) 345 x 10^{5} = 3.45 x 10^{2} x 10^{5} = 3.45 x 10^{7}

**Question 2.**

**Solution:**

(i) 3.74 x 10^{5}

= \(\\ \frac { 374 }{ 100 } \) x 10^{5}

**Question 3.**

**Solution:**

(i) Height of Mount Everest = 8848 m

= 8.848 x 1000

= 8.848 x 10^{3}

(ii) Speed of light = 300000000 m/sec.

= 3.00000000 x 100000000

= (3 x 10^{8}) m/sec.

(iii) Distance between the earth and the sun = 149600000000 m

= (1.49600000000 x 100000000000)m = (1.496 x 10^{11}) m

**Question 4.**

**Solution:**

Mass of earth = (15.97 x 10^{24}) kg

and mass of moon = (7.35 x 10^{22}) kg

= Total mass of earth and moon

**Question 5.**

**Solution:**

(i) 0.0006

= \(\\ \frac { 6 }{ 10000 } \) = \(\frac { 6 }{ { 10 }^{ 4 } }\) = 6.10^{-4}

**Question 6.**
