7√ π ^3

Not sure how to type all the math stuff but basically..

7th root of pi to the 3rd.

I have no idea why, but this equation has been stuck in my head for months.

Hi this is my first post here.

On the puzzle ABCD × E = DCBA

Should it not be, (A)(B)(C)(D) x E = (D)(C)(B)(A)

There for A, B, C, D can be anything as long as E = 1 or 0?

If this has been discussed before sorry.

Thanks all!
