Identify the number and the type of root needed
For square root, find the number that multiplied by itself gives the original number
For cube root, find the number that multiplied by itself three times gives the original number
Use a calculator if exact mental calculation is difficult
Estimate the root by checking nearby perfect squares or perfect cubes
Use prime factorization for exact roots when possible
Apply the long division method for square roots if needed
Verify the result by raising the root to the required power
If the number is not a perfect root, express it as a decimal or simplify it in radical form
