Question

Do you guys know how to find a square root or cube root without a calculator? I need a explanation and a example.

Answer 1

There’s no way besides finding the prime factors

so take 9 for an example.
start dividing by prime numbers:
9 / 2 (can’t be done)
9/3 = 3
3/3 = 1

3 is in the answer once therefore the answer is 3
