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: 5√32 = 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.
± a√b, ± d ± a√b, ± a√bc ± d√ef
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
