Since each dial on the combination lock has 10 possible digits (from 0 to 9 ), the total number of different combinations is calculated by multiplying the number of choices for each dial.

Since there are 5 dials, and each dial has 10 possible digits, the total number of different combinations can be calculated as:

\mathrm{ 10 \times 10 \times 10 \times 10 \times 10=10^5=100,000 . }

Therefore, there are 100,000 different combinations possible on the 5-dial combination lock.
