Using the ratio of perfect squares method, what is square root of 112 rounded to the nearest hundredth?
elixir [45]
First, you have to think of any perfect squares that multiply to 112. The only ones I can think of are 16 and 7. So now you have the square root of 16 * 7. Now you can reduce the 16 because the square root of 16 is 4. So the answer is 4 times the square root of 7.
