X^y

On a Casio calculator you can perform exponentiations

Xy

 

---

Example 1

To calculate 2³ = 8

					2xy3                 8.
2	Xy	3	=

and you get this also for

			2³                   8.
2	X³

Example 2

To enter 0⁰

					Ma  ERROR
0	Xy	0	=					AC/ON

although it is determined by definition that 0⁰ ≝ 1. Take that as a warning.

Example 3

To calculate (−2)⁴ = 16 where parentheses are required

										(-2)xy4             16.
(		(−)	2	)		Xy	4	=

because −2⁴ = −16

						-2xy4               -16.
(−)	2	Xy	4	=

Example 4

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

							2xy-1                0.5
2	Xy		(−)	1	=

 

---

Example 5

To calculate e^π = 23.140…

SHIFT		ex		SHIFT		π				eπ                   23.14069263
		ln				EXP		=

 

---

Example 6

To calculate 2¹ = 2

					2xy1                 2.
2	Xy	1	=

 

---

Example 7

To calculate 2⁰ = 1

					2xy0            1.
2	Xy	0	=

 

---

Example 8

To calculate 3^1/2 = 1.7320…

											3xy(1÷2)          1.732050808
3	Xy		(	1	÷	2	)		=

what you can also calculate as √3 = 1.7320...

				√3                   1.732050808
√	3	=

Example 9

To calculate

											2xy(2^3)          256.
2	Xy		(	2	Xy	3	)		=
