Best ResponseYou've already chosen the best response.1got it okay so you have to take square root both sides to cancel out the square

Best ResponseYou've already chosen the best response.1\[\huge\rm \sqrt{r^2}=\sqrt{\frac{ 9 }{ 2 }}\] square root both sides

Best ResponseYou've already chosen the best response.1\[\sqrt{r^2} = r \] square root cancels with the square because when you convert square root to exponent you will get \[\huge\rm \sqrt{r^2} = r^\frac{ \cancel{2} }{\cancel{ 2} }\] according to this exponent rule \[\large\rm \sqrt[n]{x^m} = x^\frac{ m }{ n }\]

Best ResponseYou've already chosen the best response.1now solve right side \[\sqrt{\frac{ 9 }{ 2 }}\] is same as square root of 9 and 2 \[\sqrt{\frac{ 9 }{ 2 }}=\frac{ \sqrt{9} }{ \sqrt{2} }\] you can't have the radical sign at the denominator of the fraction so that's why multiply both the denominator and numerator of the fraction by sqrt{2}(denominator)

Best ResponseYou've already chosen the best response.1so why did you write sqr{2} to the 1/2 power ?

Best ResponseYou've already chosen the best response.1actually i don't know why did you write square root AND 1/2 power

Best ResponseYou've already chosen the best response.0i actually don't know how it works..

Best ResponseYou've already chosen the best response.0but i know it's correct.

Best ResponseYou've already chosen the best response.1no \[\huge\rm \sqrt{x} = x^\frac{ 1 }{ 2 }\] 1/2 is same as square root of something

Best ResponseYou've already chosen the best response.1you can write \[\frac{ }{ 2^\frac{ 1 }{ 2 } \times 2^\frac{ 1 }{ 2 }}\] then you don't need to write square root

Best ResponseYou've already chosen the best response.0i remember who told me this i will link you to the question.

Best ResponseYou've already chosen the best response.1don't get it ? it's okay so this is the exponent rule \[\sqrt[n]{x^m}=x^\frac{m }{ n}\]

Best ResponseYou've already chosen the best response.0oh wait i think i get it

Best ResponseYou've already chosen the best response.1so square root of sqrt{2} is 2^1/2 power \[\huge\rm \sqrt{2} = 2^\frac{ 1 }{ 2 }\] when you changed to exponent form then you don't need square root
