Exponentiation

On a Microsoft calculator you can perform exponentiations with the key

xy

 


Example 1

To calculate 23 = 8

 2  xy  3  3 = 8

and you get this also with

 2  x3 8

 


Example 2

Enter 00

 0  xy  0  0 = 1

This is correct, as per definition is determined that 00 ≝ 1.

 


Example 3

To calculate 2−1 = 0.5 where you have a negative exponent

 2  xy  1  ± -1 = 0.5

what you can also calculate as the reciprocal of 2

 2  1/x 0.5

or by the division 1 / 2

 1  / 1  2  = 0.5
