Use a calculator and press the square root button
For square roots, find the number that multiplied by itself equals the original number
For cube roots, find the number that multiplied by itself three times equals the original number
Use exponent notation: root of n can be written as n^(1/2) for square root or n^(1/3) for cube root
Estimate the root by comparing nearby perfect squares or perfect cubes
Use long division or iterative methods for manual calculation
Apply Newton’s method for a fast approximation
Check your answer by multiplying it by itself the required number of times
