what is the value of the following equation?

if you assume Italian alphabeth, which has no x in it, the full answer is...\n\nx^21 - S(1)x^20 + S(2)x^19 - S(3)x^18 + S(4)x^17 - S(5)x^16 + S(6)x^15 - S(7)x^14 + S(8)x^13 - S(9)x^12 + S(10)x^11 - S(11)x^10 + S(12)x^9 - S(13)x^8 + S(14)x^7 - S(15)x^6 + S(16)x^5 - S(17)x^4 + S(18)x^3 - S(19)x^2 + S(20)x - S(21)\n\nwhere\n\nS(1) = a + b + c + d + e + f + g + h + i + l  + m + n + o + p + q + r + s + t + u + v + z\nS(2) = sum of all different products of two letters choosen in the set [ a, b, c, d, e, f, g, h, i, l, m, n, o, p, q, r, s, t, u, v, z]\nS(3) = sum of all different products of 3 letters chosen in the set  [ a, b, c, d, e, f, g, h, i, l, m, n, o, p, q, r, s, t, u, v, z]\n\n... and for each n\n\nS(n) = sum of all different products of n letters chosen in the set  [ a, b, c, d, e, f, g, h, i, l, m, n, o, p, q, r, s, t, u, v, z]\n\nso that \n\nS(21) = abcdefghilmnopqrstuvz\n\n-------\n\nif you assume the anglo-saxon alphabeth, AND YOU ASSUME THAT YOUR VARIABLE x IS THE SAME THAN THE PARAMETER x IN THE SECOND TERM OF EACH PARENTHESYS, then the answer is 0.\n\nOtherwise, you get a polynomial of the 26th order similar to the one described above, and an error in assigning the name to the variables

The error is +/- 0.01.\n\nThe value then is: 6.02 +/- 0.01

x^2+mx+1/x^2+x+1<3\n\ncase 1 : for x>0\n=> (x+1/x)^2 +(m+1)x <4\n=> (m+1)x < 4- (x+1/x)^2\n\nNow, we find the maximum value of the RHS:\nthe minimum value of (x+1/x)^2 is 2 when x=1 and for all other values of x it is >2 \nThis makes max(RHS)=0 or m+1 <0 \nor m<-1\n\ncase 2: x<0\nthe same argument as above(but x=-1)  leads us to m+1 >0 \nor m>-1\n\ncase 3: x=0\nThe given expression is undefined \n\nI guess its a home work problem, which indeed makes you lazy!

x = [-(-4) +/- root((-4)^2 - 4x1x(-5))]/2x1\n  = (4 +/- 6)/2\n  = 5 or -1

I'm sorry, but how could you not know this?\nThis is basic elementary math and if you don't know how to round you are in trouble.\nIt's 0.1 by the way

UGH!!!  Thx for the effort (I was the one to post that question, as a part of a solution to another problem I found here on Yahoo! Answers.)  Incidentally, I made a mistake when simplifying the other problem and it should be xln(2)-2ln(x)-ln(86400) = 0\n\nI don't know any way to get rid of the ln(x) unless maybe it's using calculus techniques?  I'm just glad this problem is making other ppl trouble about it as much as I did :-).

Here it is:\n\n(98,42)Mo + (1,0)n ---> (99,42)Mo

im pretty sure its λ = Rh((1/n^2) - (1/m^2)) so \nλ/Rh = 1/n^2 - 1/m^2 \nso λ/Rh + 1/m^2 = 1/n^2 \nso n^ 2 = 1((λ/Rh) + (1/m^2)\nso n = sq. root(1((λ/Rh) + (1/m^2))

Well, I can see that one possible solution is r = 0, and my calculator says the other answer is r = 0.0809394063, so hopefully that helps...

It's bringing the √2 out from the brackets. \n\nMultiply 1+(3/2) by 2... what do you get? 2+(3)\nMultiply 1+(√3/2) by √2.. what do you get √2+(√3)

It's unclear what that equation says.

lol anything to the power of 0 is equal to 1\nso the answer should be\n-1 / c

that is incomplete because you are missing one parenthesis. But x=0 is a correct answer.
