Can you explain how you got
4
and
1/9
please.
I prefer to see you post the answer, not the letters. This way you have an extra chance of checking your answer.
for questions 13 and 14 write the value of the expression
(these are fractions)
13. 3^4/3^4
A) 3
B) 0
C) 1
D) 4
14. 3^3/3^6
A) 1/27
B) 1/9
C) 9
D) -27
I think that 13 is D and that 14 is B. Am i correct?

I don't know anything about polynomials, but I can see in the first problem that the numerator and the denominator are the same.
When you divide a number by the same number, what do you get?

well, these are not polynomials. Look up the definition of polynomials.
What these are are powers to a base.
Rules
3^2 * 3^5=3*5
4^2 * 4 * -3=4^-1=1/4
5^4/5^6=5^4 * 5^-6= 5^-2=1/5^2
4^3 * 7^3...can't be combined, you have to have the same base..
a^3 * b^5/(a^4 * b^5)=
a^(3-4)*b(5-5)=a^-1 * b^0
= 1/a

Yes, what Ms. Sue said.
When you divide n pennies up evenly between n cups, you have ONE per cup.
