I am not a super smart mathematician (I'm in 9th grade), but I think I found the area of a tesseract.

Divide 980 by 2.

980/2=490

I can tell you the volume of the enclosed space in a hypersphere, but any others you may have to find on your own.

$V={1\over2}\varpi ^2R^4$

             ^

              That is actually this: π

There is no solution.

$3x+4*{-3\over4}x-2=20$

Simplify.

$3x-4*{3\over4}x-2=20$

Simplify

$3x-3x-2=20$

Combine like terms.

$-2=20$

The only problem with that answer is that it is incorrect, so therefore x has no solution.

! means factorial.

Ex. 4!=1*2*3*4

9=10 is an incorrect statement because 9 does NOT equal 10.

2m^-4/(2m^-4)^3 = 0.25[(m)^8]

You have 1/24x³.

1/(24x^3)=x = {x=((i)/24^((1/4))), x=-((1/24^((1/4)))), x=-(((i)/24^((1/4)))), x=(1/24^((1/4)))}

sqrt(200)/2 = 7.0710678118654752

Beat me to it.
