Exercise 4 Page 75

We want to find both square roots of 949. ± sqrt(9/49)We need to think of a number that when raised to the second power results in 949. By using the Power of a Quotient Law, we can see that this number is 37.

With this information, we can say that the square roots of 49144 are ± 37. ± sqrt(9/49) = ± 3/7
