1.	For a fixed base, if the exponent decreases by 1, the number becomes:(a) One-tenth of the previous number.(b) Ten times of the previous number.(c) Hundredth of the previous number.(d) Hundred times of the previous number.
Answer» (a) One-tenth of the previous number Explanation: Suppose for 10⁶, when the exponent is decreased by 1, it becomes 10⁵. Hence, 10⁵/10⁶ = 1/10.
