The Power Function

Pressing q calculates a power of a number — that is, y

x

. Like the arithmetic

function +, q requires two numbers:

1. Key in the base number (which is designated by the y on the key).
2. Press \ to separate the second number (the exponent) from the first (the

base).

3. Key in the exponent (which is designated by the x on the key).
4. Press q to calculate the power.
