Hello there!

Let me start with 8^-2
8^-2 = 1/8 * 8
8^-2 = 1/64
which equals to 0.015625 in decimal
8^ 0 = 1
Yep, that's the answer! Easy, isn't? Well you may have been wondering why 8^0 is equal to 1.
I quoted an explanation online that says: Think of "multiplication" as always including an extra "1" as a multiplier.
So it'd be like
8^ 0
8/8 = 1
Remember: Whenever a number has an exponent 0, the answer MUST be 1.
Thus,
8^0 is greater. As you can see, it is equal to 1, while the other one is equal to 0.01
I'm terrible at explaining stuff. I hope you find this answer somehow helpful :)
16x^3 + 28x^5y = 4x^3(4 + 7x^2y)
Therefore, the gcf is 4x^3
