I remembered it was something like this: Find the prime factors of a number, then group all 2's numbers, for example, to find the sq root of 144, its prime factors are 2, 2, 2, 2, 3, and 3. Then, for every two same numbers, that is equivalent to one of that number. For example, there are two 2, then, that number is equivalent to 2 only. 2, 2, 2, 2, 3, and 3 are equivalent to 2, 2, and 3. Then multiply those numbers. (2x2x3=12 12x12=144 Didn't know I would still remember it.) Merged post follows: Consecutive posts mergedP.S. If you get an extra number (2, 2, 2, 2, 3, 3, "4"), put that number inside the radical sign. (2x2x3 \/"4"" or 12\/"4"") (just pretend \/""" is radical)
