Lamplighter, it's true that 1 is a cubic square, but I think 1 is described by the x^2^3 formula.

Bruce ... yours? Congratulations.

I note that there are some that are exactly two things, some that are exactly three things, one that is exactly seven things, but none that are exactly one thing, none that are exactly four things, none that are exactly five things and none that are exactly six things.

How could there be?

Find any cubic square number. cube-root then square-root it. then quare and cube that solution, and it will have to be the same. it will HAVE to follow the x^2^3 formula.

I'm *pretty sure* that you are right, but I was wondering about a situation where x^3 = y^2 where x and y are not related in this way.

Something like 7^3 and 19^2, although of course not that.

But yeah, I don't think there can be.

With very good reason.

A new study by researchers at the University of Chicago has found that for people who get anxious at the idea of doing mathematics, just preparing to do a math problem can trigger activity in a part of your brain that registers physical pain.

Had the same effect, and indirectly, the same cause.
Of course there was the additional problem of him feeling inferior to someone as smart and attractive as you.

U so funny.

I love you long time.

For someone who has math anxiety, the anticipation of doing math prompts a similar brain reaction as when they experience pain—say, burning one’s hand on a hot stove.

Barbie said math is hard. Some people even believe philosophies taught by a doll.

Which proves a serious need for iconoclasts.

Why study math when they'll never use it ?
