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.
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
1800
5 is.
36
Powers are how many times you multiply a number by itself. Three squared (or three to the second power) is the same as 3 times 3. Three to the third power is the same as 3 times 3 times 3. This can continue forever. For the record, three to the third power is equal to 27.
four to the fifteenth add the third to the second... and multiply it by the three answer: 1073741824
5600
1,323
4 to the second power times four
31
It Is: 62*33 = 972
