How do we evaluate powers of 10?

To evaluate a power of 10, we multiply the base left parenthesis, 10, right parenthesis by itself the exponent amount of times.
Example:
10, start superscript, 5, end superscript has an exponent of 5, so we multiply 10 times itself 5 times:
10, start superscript, 5, end superscript, equals, 10, times, 10, times, 10, times, 10, times, 10, equals, 100, comma, 000

The pattern

The number of zeros in the solution always matches the exponent.
Example:
10, start superscript, start color #1fab54, 3, end color #1fab54, end superscript, equals, 10, times, 10, times, 10, equals, 1, start color #1fab54, 000, end color #1fab54, which has start color #1fab54, 3, end color #1fab54 zeros
