z=-16 is a real number & cannot hav imaginary component...so if z=a+jb then a=-16, b=0...

The math general in the house,

Nobody has done justice to the third question posed by mikebis on page 57

I believe dat he extracted the question from a textbook called bouday

u^2/v + v^2/u =12

1/v + 1/u = 1/3.
i guess nobody attemptd it 'cos its straightforwrd...multipy both eqns by uv to get, u^3+v^3=12uv,
u+v=uv/3, recall dat
u^3+v^3=(u+v)^3-3uv(u+v), d first eqn bcoms
(u+v)^3-3uv(u+v)=12uv, substitut 4 u+v frm eqn1
(uv)^3/27-(uv)^2=12uv or
(uv)^2-27uv-324=0 or
uv=0 or 36 or -9 so dat from
u+v=uv/3
u+v=0 or 12 or -3, solvin d quadratics givs, u=6,-4.85 and
v=6, 1.85

rhydex 247: Soln.
Case 1. Suppose G has an element g of order 3. Then d cyclic subgroup generated by g contains three elements.{g,g^2,g^3=e}, where e is d identity. But the order of every subgroup must divide the order of G, nd dis is a contradiction. So G has no element of order 4.
Case 2. G is nt cyclic. Thus G={e,a,b,c} where e is d identity, nd each of a,b nd c has order 2. Nw let us take a look at d multiplicatn table.
i dnt knw hw to construct a table here. Buh here is a way 4ward. Draw a multiplicatn table.The ist row is (e,a,b,c), ist column (e,a,b,c) , 2nd row is (e,a,b,c), 3rd row is (a,e,c,b), 4th row is (b,c,e,a) nd d 5th row is (c,b,a,e). Nd nw by inspection, we see dat G is abelian. All is well.

rhydex 247: solution.
Suppose we have 2 subgroups of G defined as H1 and H2. Nw the questn implies H1 intersectn H2 must also be a subgroup of G.
For any element a in H1 there exists a^-1 and H2 is closed. The same holds for H2. So the intersectn will only contain an element c in H1 intersectn H2. If c and c^-1 are in H1 and H2 they must contain e the identity of G thus H1 intersectn H2 cannot be empty. Hence the intersectn of any subgroups of a group G is a subgroup of G.

smurfy: Not bad. Here goes...
Each side has eight pawns, and each pawn can move in 2! ways. So white's first pawn move can be done in 2! * 8 ways (= 16). Each side has two knights and each knight can move in 2! ways, giving 2! * 2 (=4). So white's first two moves can be done in 16+4=20 ways. Since each side has exactly the same number of ways of moving, then, using product principle, the first two moves can be made in 20*20=400 ways. By the way, are u on chess.com? ...feel like trashing someone right now lol

smurfy: In how many ways can the first two moves (one by each player) be made in a game of chess?


What will the answer be for the first four moves (two by each player)?
...a single pawn move from white attracts 16 possible pawn moves from black...so d 16 possibl pawn moves for whit attracts a total of 256 pawn moves from black...a singl pawn move from white attracts 4 Knight moves from black, so 16 pawn moves from white attracts 64 Knight moves...a single Knight move from white attracts 16 pawn moves from black, so 4 knight moves attracts 64black pawn moves...finally, a single white's knight move attracts 4 black's knight moves, so that 4 attracts 16....so we have: 256+64+64+16=400...i guess ur second question can confidentently b answered using computer analysis...

jackpot: The bolded is just cock-and-bull.

First of all, what does the remainder theorem say?

Once a polynomial f(x) is divided by x-a, the remainder is another polynomial of 1 degree less than that of f(x) together with a remainder R still to be divided by x-a.

i.e., f(x)/(x-a)=g(x)+R/(x-a)
therefore f(x)=(x-a)g(x)+R
substituting x=a yields that
the remainder R=f(a)

back to the question. What is a polynomial? I would leave that for you to find out.

The equation x^x+y^y=13 is not a polynomial.

Why then are you applying the remainder theorem which specifically talks about polynomials?

And the funny thing is that you said the application yields y=3. SMH

Rubbish. Bros, no just dey form anyhow, you are still a BIG learner. angry

jackpot: Given that x,y,z depends on three variables, viz,
x=x(u,v,w), y=y(u,v,w), z=z(u,v,w),
we know that the three transformed equations
u=u(x,y,z), v=v(x,y,z), w=w(x,y,z) is non-degenerate if the Jacobian of the transformation doesn't vanish.

Now, consider the equation
x=x(u,v,w).
Differentiating both sides partially w.r.t. x, we have
1=Xu Ux+ Xv Vx+ Xw Wx

so, the relationship is

Xu*Ux=1-(Xv Vx + Xw Wx)

jackpot: The number is 10x+y

The problem is
maximize F(x,y)= 10x+y
subject to x+y=9
10>x,y > 0 integers
you may use Lagrange multiplier method.

solve and you'll get x=5 or 4, y=4 or 5. Thus, the number is 54 or 45. Sorry, I am quite busy.
