How to Find Cube Root on Mobile Calculator Android?

Published in Android Calculators 2 mins read

If your Android calculator doesn't have a dedicated cube root button, you can find the cube root by using the exponentiation (power) function, typically represented by a "^" symbol or "xʸ", and raising the number to the power of 1/3.

Here's how:

  1. Identify the exponentiation button: Look for a button that looks like "^" or "xʸ". This button is used to raise a number to a certain power.

  2. Enter the number: Type the number for which you want to find the cube root (e.g., 8).

  3. Press the exponentiation button: Tap the "^" or "xʸ" button.

  4. Enter the exponent: Enter "1/3" or "(1/3)". Some calculators may require parentheses to ensure the correct order of operations.

  5. Press the equals button: Tap the "=" button to calculate the result.

Example:

To find the cube root of 8:

  1. Enter "8"
  2. Press "^" (or "xʸ")
  3. Enter "(1/3)"
  4. Press "="

The calculator should display "2", which is the cube root of 8.

Important Considerations:

  • Parentheses: Using parentheses around "1/3" is crucial on some calculators to ensure the correct order of operations. Without parentheses, the calculator might interpret "8^1/3" as "(8^1)/3", which would give an incorrect result.
  • Scientific Mode: Ensure your calculator is in scientific mode to access the exponentiation function. You can usually switch to scientific mode in the calculator app's settings or by rotating your phone to landscape mode.
  • Alternative Representations: Some calculators might use different notations for exponentiation, such as "pow(x, y)" or "xy". If you see these, use them accordingly. For example, you might enter "pow(8, 1/3)" or "8(1/3)".
