For a fixed base, if the exponent decreases by 1, the number becomes ______.
Options
One-tenth of the previous number.
Ten times of the previous number.

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