# Contradiction Problem 1

### Hint

Start by writing out the negation of the claim, so you know what
your starting information is.

Remember that a
rational number is defined as a number which can be represented as a
ratio \(\frac{c}{d}\) of two integers c and d, where d is not equal to
zero.

Keep an open mind about what the contradiction will be. Try
simplifying the starting equation and see if you can produce
an equation that is obviously unreasonable.
