\n" ); document.write( "\n" ); document.write( "Rational numbers are those numbers that can be expressed as the quotient of two integers, namely

where p and q are integers. I suspect your instructor means for you to form

for the second part of this problem by using non-integer rational numbers, i.e. fractions, but the way the question is worded you could use the integer example for the rational number example since all integers are rational numbers. (That's because you can express any integer n as the rational number

by letting p = n and q = 1.)\r

(or the square root of anything that is not a perfect square),

, or the base of the natural logarithms

. Pick three of these sorts of numbers and then substitute these values for a, b, and c in
