-2 times -2 = plus 4 since minus times minus is plus
23 x 32 = 72
2 times 3 to the second power equals to 2x9 or 18 2 to the second power times 3 equals to 4x3 or 12 therefore the least common factor is 2.
Is 4 a factor of 720
5 is.
2 x 3 x 3 = 18
2 to the second power is 4, which isn't a factor of 54. 3 to the second power is 9, which is a factor of 54 but isn't prime. 4 divided by 9 is 4/9, which isn't prime and isn't a factor of 54.
2 x 2 x 2 x a x a x a x b x b
x^2(x - 4)(x + 4)
6x5
It is difficult to interpret what this question is asking. If you are making a factor tree and one of the branches is 6, this can be broken down into 2 and 3, which is a factorization of 6. Since there is only one "2" here, you would not have two to the second power.
12 to the second power is 144...2 to the second power is 4, any # to the second power is the # times itself.
