I am evaluating the following correct to 4 sig figures. I am having difficulty with this particular one and I thought there might be someone who could lend a helping hand.

5*[6.2+(4.3)2] <= The "2" is square
--------------
21-[0.18/(0.3)2] <= The "2" is square

What I have been doing is evaluating the numbers contained in the brackets and then going from left to right. However I seem to always end up with the wrong sum.

However I did this one and got it correct:

15.023*(0.1)2 <= The "2" is square
----------------
_____________
3\/56-(-63)+(-5)

Answer: 0.003098

Thanks in advance for the help.
