RIGHT the transfermation a reflection I think idk
You need the greatest common factor of the two numbers.
First, we find the prime factorization of each number.
72/2 = 36
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1
72 = 2^3 * 3^2
90/2 = 45
45/3 = 15
15/3 = 5
5/5 = 1
90 = 2 * 3^2 * 5
To find the GCF, use only common factors with the lower exponent.
Both 72 and 90 have 2 as a factor. 72 has 2^3, and 90 has 2. 2 has a lower exponent than 2^3, so we use 2.
Both 72 and 90 have 3 as a factor. The both have 3^2, so we use 3^2.
90 has 5 as a factor, but 72 does not, so 5 is not a common factor, so we do not use 5.
The GCF is the product of the factor we use.
GCF = 2 * 3^2 = 2 * 9 = 18
Answer: The greatest number of students he can place in a row is 18.
Umm hi how are you today keep going and dont cheet h

8. I can't see
One thing you want to make sure you do is move all terms with variables to one side and the constant terms to the other. It makes it so much easier to evaluate the variables once you do.
Answer:
![8^2, 4^3, 2^6](https://tex.z-dn.net/?f=8%5E2%2C%204%5E3%2C%20%202%5E6)
Step-by-step explanation:
8 x 8 = 64
4 x 4 x 4 = 64
2 x 2 x 2 x 2 x 2 x 2 = 64
