What do i do with the a^2
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
a 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

same principle is used. (4x^4)^1/2, 4*(1/2)=2= 2x^2

dave0616Best ResponseYou've already chosen the best response.1
that 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

That would be the answer? ^^^

dave0616Best ResponseYou've already chosen the best response.1
nope, because you origonally had :\[\sqrt{x^{4}}\] and you took the square root of that to get x^2

So what would it be? Just x^2

\(\large \sqrt{9x^4}= 3x^2\) is correct.
 one year ago

dave0616Best 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
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
ohhhh i mistook that as a four, im sorry, then yes 3x^2 would be correct
