Square root of 2x^2?

[ViperMagic]

Yeah, stupid question I know, but I forgot how to get it

 

[XZeroII]

Sqrt(2) * X

 

[AkumaX]

uh... (square root of 2 = 1.414...) * x?

 

[Random Variable]

(2)^(1/2)*|x|

The way that's written, the answer could just be 2x.

As in... square root of ((2x)^2).

Ain't it fun not being able to use mathematical symbols in posts.

Order of operations. By defalt exponents are calculated before multipication.

 

[bizmark]

+/- sqrt(2)*x

don't forget the +/-!

again, that's assuming the order of operations is correct, i.e. it's 2*(x^2) not (2*x)^2
