Is a group of order 5 always abelian

Yes.Let G be any group of order 5, and let x be any element of G that isnt the identity.Consider the subgroup H of G generated by the element x (ie, the set {x^n: n is an integer}).By Lagranges theore

How do i find all zeros of polynomial x^5+4x^3+8x^2+32

so far what what I have is x^3(x^2+4)+8(x^2+4)= (x^3+8)(x^2+4) I am stuck otherwise If you can please show me how to approach the rest of find all zeros I greatly appreciateit thanks.-= (x^3+8)(x^2+4)

(beginning calculus) I need help finding a limit of this graph

Heres the graph i drew http://tinypic.com/r/26oaf/7 (the black part is the actual graph, the gray is the asymptotes) I need help finding the lim of this graph as x approaches infinity? Also, it wou

Compute the limit. very hard problem! i need help!

compute the limit as x -------> 9- of: (x-1)/(x-9) * (int(t^t dt) from x to 9)-Note that this limit can be re-written as: lim (x-->9-) [(x - 1)/(x - 9) * ∫ t^t dt (from t=x to 9)] = lim (x-->9-) [(x -

I have trouble determining when to use 0 So if anybody knows how to tell when the convergence interval starts at 0, please share. Thanks :P-for example: if we end up with x + 2 > 1 to find the inte

How do you factor (x^3)-1

Its the difference of two cubes: x^3 - 1 = (x - 1)(x^2 + x + 1)-x^3 - 1 is the difference of two cubes... (x - 1)(x^2 + x + 1) check...read your textbook...learn sum and difference of two cubes...

What are the zeros of -8x^3-7x^2+x

I am not sure how to find the zeros for this problem can anyone explain how to approach this problem.Thankyou for your time.--8x³ - 7x² + x = 0 -x(8x² + 7x - 1) = 0 {factored -x out} -x(8x - 1)(x + 1)

If you're good at Customary System math problems, please me with this question.

I dont know the answer to this problem, i thought the answer was 3 yards and 33 feet, but it doesnt. look right. 10 feet = _____yards_____feet If my answer was right, then how i would i do this one:

Prove that the Maclaurin series for any polynomial is the polynomial itself

The Maclaurin series for (1-x)^-1 for |x| 1+x+x^2+x^3+........... so the Toylor series for x^-1 at a=1 is 1-(x-1)+(x-1)^2-(x-1)^3+.......... By integrating the above Maclaurin series we find the s

If you have 2400 cm2 of material available to cover a cube;

Then what is the maximum volume of the cube?-let its side length = x => 2400 = 6x^2 => x^2 = 400 => x = 20 cm so its volume = 20^3 = 8000 cm^3-Both the surface area and the volume of a cube depends
