Math CentralQuandaries & Queries


Question from Lauren, a student:

How do you solve square roots of fractions? Does the format change if it is either a proper or an improper fraction?

Ex. the square root of 1/4 or the square roots of 80/25


You can use the fact that rootsso roots

For 80/25 you can apply the same technique or you could notice that 5 divides the numerator and denominator and hence write 80/25 = 16/5 before taking the square root of the numerator and denominator.

I hope this helps,
