विकल्प

• One-tenth of the previous number.

• Ten times of the previous number.

Answer 1

For a fixed base, if the exponent decreases by 1, the number becomes one-tenth of the previous number.

Explanation:

If the exponent is decreased by 1, then for the fixed base, the number becomes one-tenth of the previous number.

E.g. - For 10⁵, exponent decrease by 1

⇒ `10^(5 - 1) = 10^4`

⇒ `10^4/10^5 = 1/10`
