Calculate the power of a number ($base^{exponent}$).
When the exponent is a positive integer, it means multiplying the base by itself that many times.
Example: "3 to the power of 2" is $3 \times 3 = 9$.
A negative exponent tells you to divide 1 by the base raised to the positive version of the exponent.
The result is a fraction (or decimal) less than 1.
Any number (except 0) raised to the power of 0 is always 1.
Zero raised to any positive exponent is always 0.
Note: 00 is mathematically undefined/indeterminate.
