Powers, Power Roots, and Reciprocals

Use the keys below to input power functions, power root functions, and reciprocal function.

Power functions: (square), (nth power)

Power root functions: (square root), () (nth root)

Reciprocal function: ()


Example 1: (52)3 = 15625

  • 53

Example 2: (1 + 1)2+2 = 16

  • 1122

Example 3: 2 × 3 = 3√2 = 4.242640687...

(Input/Output: MathI/MathO)

  • 23

(Input/Output: LineI/LineO)

  • 23

Example 4: 532 = 2

(Input/Output: MathI/MathO)

  • () 532

(Input/Output: LineI/LineO)

  • 5() 32

Example 5: 10-1 = 110

(Input/Output: MathI/MathO)

  • 10()

Key (Power of 10)

Pressing the key is the same as pressing . Both operations input "×10" (MathI/MathO or MathI/DecimalO) or "×10^(" (LineI/LineO or LineI/DecimalO).


Example: 1.23 × 103 = 1230

  • 1233

  Form Calculation Range

The allowable display ranges of the √  form calculation result are shown below.


± ab, ± d ± ab, ± abc ± def

1 ≤ a < 100, 1 < b < 1000, 1 ≤ c < 100
0 ≤ d < 100, 0 ≤ e < 1000, 1 ≤ f < 100


Example:

10√2 + 15 × 3√3 = 45√3 + 10√2 ... Displayed in √  form

99√999 (= 297√111) = 3129.089165 ... Displayed as a decimal value
