Re: simplify
Why are you using decimal approximations instead of the exact form? (Did the instructions, not included in your post, say to do this?)
Thank you.

Do you mean what you posted, 3 - (sqrt[2])/4 + 2sqrt[2], or (3 - sqrt[2])/(4 + 2sqrt[2]), or something else?humakhan said:

Re: simplify
\(\displaystyle \L\,3 - \frac{\sqrt{2}}{4} + 2\sqrt{2} = 3 + \frac{7}{4}\sqrt{2}\)
You have used sloppy notation for so long that you have forgotten the order of operations. Clean it up.
You worked on this problem: \(\displaystyle \L\,\frac{3-\sqrt{2}}{4+2\sqrt{2}}\) That is very different and is NOT what was written.

Either use the suggested grouping symbols:
. . . . .(3 - sqrt[2]) / (4 + 2sqrt[2])
...or else follow the links in the "Forum Help" pull-down menu at the very top of this page, and learn how to use LaTeX or the standard text formatting explained at the "Karl's Notes" link.
Thank you.
