To find the cube root on a TI-84, press the [MATH] button, scroll down to select option 4 (the cube root symbol: ³√ ), press [ENTER], type your number, and press [ENTER] again for the result, or raise the number to the 1/3 power using the ^ (caret) key.
What is the Value of the Cube Root of 84? We can express 84 as 2 × 2 × 3 × 7 i.e. ∛84 = ∛(2 × 2 × 3 × 7) = 4.37952. Therefore, the value of the cube root of 84 is 4.37952.
The value of the cube root of 3 is equal to 1.44224957031. Cube root of 3 in radical form is represented as 3√3 and in exponential form as 31/3.
You can write "I love you" in a calculator by typing numbers that look like letters when flipped upside down, like 710734 (spells hELLO) or using the number sequence 143, which means "I love you" (one, four, three letters). For a visual trick, type 371073 and flip it, or use 17734 for "hello".
So, here the cube root is cancelled by the cube of 9. Hence, 3√729 = 9.
The cube root of 8000 is the number which when multiplied by itself three times gives the product as 8000. Since 8000 can be expressed as 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5. Therefore, the cube root of 8000 = ∛(2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5) = 20.
Example: Compute the cube root of 27.
