What is the cube root of 25?

The cube root of 25 is cbrt25. In decimal: cbrt(25) approximately 2.9240177382 This is irrational. cbrt(25) approx 2.92402 is irrational. 25 = 5^2, cbrt(25) = 5^(2/3). Not a perfect cube.

Is 25 a perfect cube?

No. 25 is not a perfect cube. 2^3 = 8 and 3^3 = 27. Since 25 falls between these, cbrt(25) is not an integer. Nearest perfect cubes: 8 (= 2^3) and 27 (= 3^3).

What is cbrt(25) cubed?

(cbrt(25))^3 = 25. This follows from the definition: cbrt(n) is the number that when cubed gives n. So (cbrt(25))^3 = 25 always.

How is cube root different from square root?

Square root: sqrt(25) approximately 5.000000. Cube root: cbrt(25) approximately 2.924018. Key differences: - Cube roots exist for negative numbers: cbrt(-8) = -2. Square roots of negatives are imaginary. - Cube roots grow more slowly than square roots. - Perfect cubes are rarer than perfect squares.

What are the perfect cubes from 1 to 30?

Only three: 1 (= 1^3), 8 (= 2^3), and 27 (= 3^3). 25 is not a perfect cube. The next perfect cube after 27 is 64 (= 4^3).

HOW TO CALCULATE

1
Find the prime factorisation of 25: 25 = 5 x 5. Look for any prime appearing 3+ times.
2
No factor appears 3+ times, so cbrt(25) cannot be simplified and stays as cbrt(25).
3
Locate cbrt(25) between integers: 2^3 = 8 < 25 < 27 = 3^3. So cbrt(25) is between 2 and 3.
4
Decimal: cbrt(25) approximately 2.9240177382. Verify: (2.924018)^3 approximately 25.

WORKED EXAMPLE

cbrt(25): not a perfect cube. Factorisation: 25 = 5 x 5. Simplified: cbrt25. Decimal: cbrt(25) approximately 2.9240177382.
