Rationalize the denominator of $\displaystyle \frac{1}{\sqrt{2} + \sqrt{3} + \sqrt{7}}$, and write your answer in the form A√2+B√3+C√7+D√EF,where everything is in simplest radical form and the fraction is in lowest terms. What is $A + B + C + D + E + F$?
+104 does this help? https://www.mathportal.org/calculators/radical-expressions/rationalize-radical-denominator.php
if not can you make the question neater?
