Best ResponseYou've already chosen the best response.0What do i do with the a^2

Best ResponseYou've already chosen the best response.1a is squared, and the opposite of a square root is to the second power. because this expression can also be written as (4a^2)^1/2. so if you take 2 and multiply it by a half, you get 1. so the answer is 2a

Best ResponseYou've already chosen the best response.1same principle is used. (4x^4)^1/2, 4*(1/2)=2= 2x^2

Best ResponseYou've already chosen the best response.0you can only pull two x's out right?

Best ResponseYou've already chosen the best response.1that is correct. so now you have sqrt(x^4). well in a way yes, but lets go ahead and use the formula we had.: (x^4)^1/2 4*(1/2)=2

Best ResponseYou've already chosen the best response.0That would be the answer? ^^^

Best ResponseYou've already chosen the best response.1nope, because you origonally had :\[\sqrt{x^{4}}\] and you took the square root of that to get x^2

Best ResponseYou've already chosen the best response.0So what would it be? Just x^2

Best ResponseYou've already chosen the best response.0\(\large \sqrt{9x^4}= 3x^2\) is correct.

Best ResponseYou've already chosen the best response.1@hartnn and @hogie i guess i am confused as to where the sqrt(9x^4) came from, because i dont see that any where, thought 3x^2 would be correct for that

Best ResponseYou've already chosen the best response.1ohhhh i mistook that as a four, im sorry, then yes 3x^2 would be correct
