The Power Function in RPN Mode
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
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.
4. Press q to calculate the power.

The Power Function in ALG Mode
To calculate a power of a number, that is, y
x
, in ALG mode, do the following:
1. Key in the base number (which is designated by the y on the key).
2. Press q and key in the exponent (which is designated by the x on the key)
3. Press } to calculate the power.
