It's something about monomials. I fucked off in class and didn't listen so can you explain how you got the answer. You will be my hero.
Heres the problem.
x^3 y^0 x^-7

Im pretty sure you are simplifying the monomials; so here it is.
1. Anything to the power of 0 is 1; so I rewrote y^0.
2. Anytime you have 2 of the same terms, whether same exponent or not, you add the exponents.
3. If the exponent is a negative value, put it under 1 in fraction form.
Done.

OK so I see. But I don't get why you took away the 1. I know you took away the negative on the exponent and put a 1 on top but what happened to the 1 in the middle? Does it just disappear?

Well, anything multiplied by 1 is the value itself.
You dont write 3x in the format of 1(3x) because it will still equal 3x.
Or 2 in the form of 1(2) because it will equal 2. So 1 is there, but no one writes it because its unnecessary.

Or 2 in the form of 1(2) because it will equal 2. So 1 is there, but its invisible.
