^
On a TI calculator you can perform exponentiations
∧
or via the catalog as
CATALOG ⎵
2nd 0 ►^ ENTER
Example 1
To calculate 23 = 8
2 ∧ 3 ENTER 2^3 8
Example 2
To enter 00
ERR:DOMAIN
1:Quit
2:Goto0 ∧ 0 ENTER CLEAR
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 ) ∧ 4 ENTER (-2)^4 16
as –24 = –16
(–) 2 ∧ 4 ENTER -2^4 -16
Example 4
To calculate 2−1 = 0.5 where you have a negative exponent
2 ∧ (–) 1 ENTER 2^-1 .5
or as
2 x⁻¹ ENTER 2⁻¹ .5
Example 5
To calculate eπ = 23.1406…
e x S π H 2nd LN 2nd ∧ ENTER e^(π 23.14069263
Example 6
To calculate 21 = 2
2 ∧ 1 ENTER 2^1 2
Example 7
To calculate 20 = 1
2 ∧ 0 ENTER 2^0 1
Example 8
To calculate 31/2 = 1.7320…
3 ∧ ( 1 ÷ 2 ENTER 3^(1/2 1.732050808
because after all, you can also calculate that as √3 = 1.7320...
√ I 2nd x² 3 ENTER √(3 1.732050808
Example 9
To calculate  BLAUW.gif){kind=small}
2 ∧ ( 2 ∧ 3 ENTER 2^(2^3 256
as it does not work correct without parenthesis
2 ∧ 2 ∧ 3 ENTER 2^2^3 64
Example 10
To calculate i i = 0.2078...
i : i : 2nd • ∧ 2nd • ENTER i^i .2078795764
