Use a caret ( ^ ) and type the fraction in parentheses. For example, to enter the cube root of x or x to the 1/3 power type “x^(1/3).”
Hold down the “Alt” key and type “0179” without quotes . When you release the “Alt” key, the cubed symbol appears.
Press the alt key and type 8730 using numeric keypad to make square root √ symbol. Only on Microsoft Word documents, type 221B and press alt and x keys to make cube root symbol ∛. Press “Win + ;” keys to open Windows emoji keyboard.
The square of a number is the number times itself. For example the square of 3 is 3×3 .
Since 2 & 5 do not occur in triplets. ∴ 400 is not a perfect cube .
Hold down Alt and key in 0178 and let go of Alt . A superscript 2 will appear. Incidentally, if you needed ‘cubed’ instead of ‘squared’ then type 0179 and you’ll get a superscript 3. In fact, this will work anywhere in Windows or online – even in Word.
ALT KEY. ALT KEY default position is identified by White Arrow . ALT key default position provides alphabets in small letters and let you use numerical & symbol keys depends on Gboard settings.
| 0 Squared = 0 | 3 Squared = 9 | 4 Squared = 16 | 5 Squared = 25 | 6 Squared = 36 |

3 to the second power can be written as 3 2 = 3 × 3 , as 3 is multiplied by itself 2 times. Here, 3 is called the “base” and 2 is called the “exponent” or “power.” In general, x n means that x is multiplied by itself for n times. 3 × 3 = 3 2 = 9.
As the cube root of 1000 is a whole number, 1000 is a perfect cube .
Answer: Since 2 & 5 do not occur in triplets . ∴ 400 is not a perfect cube.
