# The diameter of the Sun is 1.4 × 10⁹ m and the diameter of the Earth is 1.2756 × 10⁷ m. Compare their diameters by division.

**Solution:**

Given, the __diameter__ of the Sun is 1.4 × 10⁹ m.

The diameter of the Earth is 1.2756 × 10⁷ m.

We have to compare the diameters by __division__.

According to the question,

Division = 1.4 × 10⁹ / 1.2756 × 10⁷

= (1.4/1.2756) × (10⁹/10⁷)

= 1.0975 × (10⁹/10⁷)

Using the __law of exponents__,

a^{m} ÷ a^{n} = a^{m - n}

= 1.0975 × 10^{9 - 7}

= 1.0975 × 10²

= 1.0975 × 100

= 109.75

= 110

Therefore, the diameter of the Sun is nearly 110 times the diameter of the Earth.
