I hate questions like these...brackets should ALWAYS be used!

$\displaystyle 5-4\sqrt(3*7-5)=5-(4*\sqrt(16))$

You see, its actually -4 MULTIPLIED by the squareroot not (5-4) multiplied by the square root.

In the end you get...

$\displaystyle 5-(4*4)=5-16=-11$

Hope that helps! - Jan 24th 2007, 06:01 AMAsh
