Power Functions and Power Root Functions
Note that the input methods for , , , and are different depending upon whether you are using Natural Display or Linear Display.
Example 1: 1.2 × 103 = 1200 (MthIO-MathO)
- 12103
- 1200
Example 2: (1 + 1)2+2 = 16 (MthIO-MathO)
- 1122
- 16
Example 3: (52)3 = 15625
- 5(x3)
- 15625
Example 4: 5√32 = 2
- (MthlO-MathO) () 532
- 2
- (LinelO) 5() 32
- 2
Example 5: To calculate √2 × 3 (= 3√2 = 4.242640687...) to three decimal places (Fix 3)
- (SETUP)(Fix)
- (MthIO-MathO) 2
- 3√2
- 4.243
- (LineIO) 23
- 4.243
Example 6: 3√5 + 3√-27 = -1.290024053
- (LineIO) () 5
()27 - -1.290024053
Example 7: 113 - 14 = 12

Note
The following functions cannot be input in consecutive sequence: x2, x3, , x-1. If you input 2, for example, the final will be ignored. To input 222 , input 2, press the key, and then press (MthIO-MathO).
x2, x3, x-1 can be used in complex number calculations.
