-3y^4/5+72=-15

-3y^4/5=-87

y^4/5=29

y=29^5/4

What next? Round answer to two decimal places. Thanks for your help.

**jim**, Saturday, October 24, 2009 at 6:16pmYou'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.
