Shared fishes being equal, 3^balance=1

Richiez:

nice try bro, although you made some some mistakes especially at the point where you took log of both sides. e.g it ought to be log(x+y)= log5 and not logx + logy = log5. but i must admit, you did a very good job.

here's another approach;

x + y = 5.......(1)
x^x + y^y =31.......(2)

from eqn(1), x=5-y, hence we substitute this value for x in eqn(2).
(5-y)^(5-y) + y^y = 31.......(3)
now, we have reduced the problem to what value of y that must be inserted in eqn (3) to obtain 31.

a thorough look at eqns (1) & (2) shows that the values of x & y must be positive integers within the range 0<x<5 and 0<y<5
clearly, y=3
i.e (5-3)^(5-3) + 3^3
2^2 + 27
4+27=31
now that we have established that y=3, we shall substitute the value of y in eqn(1) to get x
recall that x+y=5
therefore; x+3=5 or x=5-3=2
hence, x=2 when y=3
Great! Actually, †ђε question has two solutions
(i) x=2 when y=3 or
(ii) x=3 when y=2

Eze Promoe: I LOVE THIS THREAD AND I'LL LOVE THE MATHS GURU TO SOLVE THIS EQUATION FOR ME!

A boy, X sleeped with my girlfriend, Y and produced 2 kids (2XY), using the onyonyo meter I saw that the pikins is not my own shildren. If Y is 22 years old and her name is Gracie
i)find X?
ii)find X's father, X^2
iii)can X beat me, Z if we fight?


Do that equation quick before i go gaga angry

Soln
find the LCM of your girlfriend, the value must be equal to X when multiplied by itself, other wise the child must have come from u, i think that answers questn i. for question ii, (X^2 = the answer from (i)^2 as u got from questin i.) then find the cosine using scientific calculator and square both sides. final answer, YES X can beat u if u Bleep up anytime anyday, provided u dnt come in the way between him and his sweetie pie. just play ur game and let him have his ok? any other question?

PortHarcourtBoy: Una say na "Mathematics" thread meanwhile all of una dey speak "English"

Some dey solve Indices, others dey solve Simultaneous equations...very soon another person go come solve Quadratic equations...abi na SS1 students dey here?

Wey the Engineers dem make we solve some First Order Differential Equations...and apply am to Fluid transfer and Thermodynamics

Meanwhile wey my Gala and La Casera?
so, solving first order differential equations and applying them to thermodynamics makes you a math guru. Guy u be serious learner.

ultranet: pls can u solve dis question: 3^x=9x...(interested in d working)

Wow! Merely looking @ dis problm, there is no direct algebraic manipulation that one can carry out on it. Tho it look like smthin that require simple logarithm or indices laws. However plotting d graphs of y = 3^x and y = 9x on d same page shows that thr is point of intersection @ y = 3 which is correct. But thr are two solutions. Let's try calculus
3^x = 9x from here, we see that:

3^x/3^2 = x
3^(x - 2) = x
Taking d natural logarithm of both sides and introducin variable y:

y = (x - 2)ln3 - ln3 and differentiating y wrt x:
y' = ln3 - 1/x

For x > 3, y' > 0 because 1/x in d range x>3 is always less than ln3 which makes y' > 0 and dis has value 0.13.
I remember a Lambert W function which can be used to solve all forms of algebraic expression that defies analytical solution. I can't remember the procedures now as I have to do a little research to get it.

I hope dis help but note that there is no numerical or analytical solutions to this problm

Re: Nairaland Mathematics Clinic by dabrake(m): 12:29pm On Jan 03, 2013
1stknight:

I believe that your equation is logically correct, if 0/0=c no matter the value of c you will still get the same answer. Therefore, 0/0 does not mean any particular number - or even anything until we give it some new meaning. And you my brother gave the value to be 12 and bro I can as well as you to cross multiply to make 0=0.
Bottom line is 0/0 is nothing
that's something about mathematics. I believe people say 0/0 = undefined because it can give you any value. Take for instance.

0/0 = (81 - 81)/(81 - 81) //81-81=0
=[(9 + 9)(9 - 9)]/9(9 -9) // 81 - 81 = 92 - 92(law of difference of 2 squares)
=(9 + 9)(9 - 9)/9(9 -9)
=(9 + 9)/9
= 2

now saying 0/0 = 12
0/0 = (144-144)/(24-24) // 144-144 =0 ; 24-24 =0
= (122-122)/2(12-12)
= (12+12)(12-12)/2(12-12)
= (12+12)/2
= 12


You see, you can always get any answer. Deceptive subject

Re: Nairaland Mathematics Clinic by chikis(m): 12:47pm On Jan 03, 2013
Youngsage:
x + y =5 -------- eqn i.
x^x + y^y=31 ----- eqn ii.
From equatns i & ii, take the log of both sides
(xlog^x + ylog^y) = log 31------ eqn iii.
logx + logy = log 5 ------------ eqn iv.
xylogxy= log 31 -------- eqn v.
log xy = log 5 --------- eqn vi.
(Using elimination method);
xylog5 = log31
xy = log 31/log 5 =6.2 approx. 6.

Recall, from eqn i, x + y = 5.
So x = 6/y or y = 6/x.
Therefore x=2 when y=3.
ans: x=2, and y=3.

substitute 5-y for x in equation2 // if x+y=5 ; y =5-x
you have x2 + (5-x)2 = 31
= x2 + 25 -10x +x2 = 31
= 2x2 -10x - 6 = 0 // a quadratic equation.
