(285714) ̅. To determine the denominator, we subtract the lower perfect square from the upper perfect square, the perfect square root that comes directly after the imperfect square root you are approximating. and career path that can help you find the school that's right for you. (If $\frac {\sqrt 2 +\sqrt 3}2 = r$ where $r$ is rational, then $\frac {2 +2\sqrt 6 + 3}4 = r^2$ and $\sqrt 6 = \frac {4r^2 - 5}2$. And $\sqrt 3\approx 1.73205....$ and certainly $\sqrt 3 > 1.73$. For example, turning pi into a fraction, start with 3.14. So if we can find an irrational number between $1.42$ and $1.73$ we will be done. credit by exam that is accepted by over 1,500 colleges and universities.
