How can this expression be solved? please help

Answer 1

Answer: if you know the square find the GCF

Step-by-step explanation: List the prime factors of each number.

Circle every common prime factor — that is, every prime factor that's a factor of every number in the set.

Multiply all the circled numbers. The result is the GCF. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
