The question:

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.
