∧

On a Casio calculator you can perform exponentiations

∧

 

---

Example 1

To calculate 2³ = 8

2	^	3	=		2^3            8.

and you get this also for

2	x3		23            8.

Example 2

To enter 0⁰

0	^	0	=		Math ERROR			AC

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

 

---

Example 3

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

(		−	2	)		^	4	=		(-2)^4           16.

because −2⁴ = −16

−	2	^	4	=		-2^4          -16.

Example 4

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

2	^		(−)	1	=		2^-1          0.5

 

---

Example 5

To calculate e^π = 23.1406…

ln

∧

EXP

=

e^π  23.14069263

 

---

Example 6

To calculate 2¹ = 2

2	^	1	=		2^1            2.

 

---

Example 7

To calculate 2⁰ = 1

2	^	0	=		2^0            1.

 

---

Example 8

To calculate 3^1/2 = 1.7320…

3	^		(	1	÷	2	)		=		3^(1÷2)  1.732050808

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

√	3	=		√3  1.732050808

 

---

Example 9

To calculate

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