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

  • (MthIO-MathO)  () 532
  • 2
  • (LineIO)  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

  • (LineIO)  34
  • 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.
