# Thread: How would i Simplify if possible?

1. ## How would i Simplify if possible?

Hello,

Is there anyway of simplifying the following, if so could someone please show me how?

[(-2F)^2+((2F)^(1/2)*sin(pi/4)+(2F)^(1/2)*sin(pi/4))^2]^(1/2)

Regards

Matt

But $( - 2F)^2 = 4F^2$ and $\sqrt {2F} \sin \left( {\frac{\pi }{4}} \right) = \sqrt F$.
