Ernst Kummer tried in vain to prove Fermat's Last Theorem, and his method (similar to Fermat's own) broke down because not all rings have the "nice" property of unique factorization. Studying these unique factorization domains did not lead to a proof of Fermat's Last Theorem, but it did lead to the study of these: a. Prime numbers
b. Algebraic numbers
c. Ideals
d. Ring generators

c. Ideals

Step-by-step explanation:

Ernst Kummer had studied ideals, the others were not studied by him.

I think its a. Prime numbers

Step-by-step explanation:

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
