 May 23, 2011 Simplifying Radical Expressions by: Staff The question: by Bob (NY) what is the square root of 21/49 The answer: sqrt(21/49) = sqrt(21)/sqrt(49) = sqrt(21)/7 Since you want to simplify the radical expression, this is probably the answer you are looking for: sqrt(21/49) = sqrt(21)/7 However, if you want to compute a decimal answer: sqrt(21)/7 = (4.58258)/7 = 0.654654 The final answer is: sqrt(21/49) = 0.654654 You could also approach the problem in a different way: sqrt(21/49) = sqrt((3*7)/(7*7)) = sqrt(3/7) = sqrt(3)/sqrt(7) = 1.73205/2.64575 = 0.654654 Thanks for writing.
