Best ResponseYou've already chosen the best response.0\[\sqrt{\frac{ 9 }{ 28 }}\] is the same \[\frac{ \sqrt{9} }{ \sqrt{28} }\] do you know how to solve \[\sqrt{9}\] and \[\sqrt{28}\] ?

Best ResponseYou've already chosen the best response.0radical 9, is the same as the square root of 9. Square root and radical mean: what number when multiplied by itself equals x. For example, what is the square root of 4? is asking what number multiplied by itself = 4? The answer is 2 because 2*2 = 4. What is the square root of 9 is asking what number multiplied by itself = 9? Post the answer and I'll help you through the square root of 28

Best ResponseYou've already chosen the best response.0Good. Since the square root of 4 is 2. \[\sqrt{4*7}=2\sqrt{7}\] Are you ok now with the final answer?

Best ResponseYou've already chosen the best response.03 will stay in the numerator, and the denominator will be 4 radical 7. Your final answer is \[\sqrt{\frac{ 9 }{ 28 }}= \frac{ 3 }{ 2\sqrt{7} }\] In a post 10 minutes ago I wrote this out with more steps

Best ResponseYou've already chosen the best response.0I made a typo in previous post. I meant to write "3 will stay in the numerator and the denominator stays "2" radical 7"
