MCQ
For a fixed base, if the exponent decreases by $1,$ the number becomes:
- ✓One-tenth of the previous number.
- BTen times of the previous number.
- CHundredth of the previous number.
- DHundred times of the previous number.
✓
Answer
Correct option: A.
One-tenth of the previous number.
For a fixed base, if the exponent decreases by $1,$ the number becomes one-tenth of the previous number.
e.g. For $105,$ exponent decreases by $1.$
i.e. $10^{5-1} = 10^4$
$\therefore\ \frac{10^4}{10^5}=\frac{1}{10}$
Note:
Option $(a)$ is possibal only, if we taken base as $10.$
e.g. For $105,$ exponent decreases by $1.$
i.e. $10^{5-1} = 10^4$
$\therefore\ \frac{10^4}{10^5}=\frac{1}{10}$
