Rational or not? (Posted on 2015-05-29) Difficulty: 2 of 5
If I enter the expression

35+42√2

into my graphing calculator and then ask it for the fractional (rational) equivalent it cannot do so. Since the number is irrational it displays the first few decimal digits:

94.39696962

However, if I enter the expression

55+42√2

into the same graphing calculator and then ask it for the fractional equivalent it displays:
37751
-----
 330 
But this second number I entered is clearly not rational either.

What's going on?
