: 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
write "squared" like this: (4.3)^2
[6.2+(4.3)^2] = 6.2 + 18.49 = 24.69
24.69 * 5 = 123.45
[0.18/(0.3)^2] = .18 / .09 = .09
21 - .09 = 20.91
123.45 / 20.91 = 5.90387374......Home, James!
