About HyperBrain: As I help you solve the problem, you are helping me practice my skills.
You don't have to memorize tremendous number to master this skill.
You need one thing----prime factorization
Ex. what is the square root of 144.
Prime factorization:
144=2%2A72
144=2%2A%282%2A36%29
144=2%2A2%2A%282%2A18%29
144=2%2A2%2A2%2A%282%2A9%29
144=2%2A2%2A2%2A2%2A3%2A3
144=%282%5E4%29%2A%283%5E2%29
Thus, sqrt%28144%29=sqrt%28%282%5E4%29%2A%283%5E2%29%29=%282%5E2%29%2A3=4%2A3=12
Gets?
