I need help with the following problem. I do not understand how to finish working it.
What next? Round answer to two decimal places. Thanks for your help.
Ok, round the answer.
You're right so far, which was the hard bit.
Me, I'd just pull out the calculator at this point. I did, and got 67.2972 = 67.30 to 2 d.p.
You can do it by = 29 * sqrt(sqrt(29)) or by log tables. I can't think of an especially clever way.
