(((3x^-3(y^2))^-3)/(-6x^3(y^-4)))^-2

ok, if i were to verbalize it- it would read The quantity of3x to the neg. 3rd times y squared to the neg. 3rd power over the quantity of -6x to the third times y to the neg fourth power. then put that whole division problem to the -2 power.

thanks!!

I know what the p-norm is, and I know how to calculate the infinite norm, but what IS it. What exactly is it used for, and was it more of an "invention" or does it have some sort of mathematical/physical meaning? Neither mathworld nor wikipedia do justice to this construct. Please help!

Suppose that the surface of the earth is smooth and spherical and that the distance around the equator is 25,500 miles. A steel band is made to fit tightly around the earth at the equator, then the band is cut and a piece of band 21 feet long is inserted. To the nearest inch, what will be the gap, all the way around, between the band and the earth's surface? (Use 3.14 as an approximate value of Pi)

Best Answer is given to the first correct answer AND who shows the best work.
