Mr Calculus: find x if 8^x=4x

here is d solutn dude..
8^x=4x
log both side
log8^x=log4x
usn rule of log,dat wen u av logab is =loga+logb
xo i av
log8^x=log4+logx
log2^3x=log2^2+logx
3xlog2=2log2+logx
3xlog2-2log2=logx
log2(3x-2)=logx
divid both side by log
2(3x+2)=x
6x+4=x
6x-x=4
5x=4
x=4/5..
Dat d ansa,did i av sm respect 4rm u nw,am nt bn proub,dnt mind me,jst jokn,we are frnds,nd i respect u nd i xpect u to do d same.i cn 2 u ard guru in math thread also.
Stl waitin 4 d soltn of ma own questn
(x/2)^x=16

Odilop: it is ascomycota and basidomycota

ascomycota or ascomycetes nd basidomycota or basidiomycetes,i tink u shld concida ma own spelln,in biology u dnt spell wt mistakes*winks*no offence

Menh u na don slip,chai..u guz wll observe dat i dnt answer much questn on biology,because am nt dat gud in biology,buh buildn ma self sha,hey buh dat dosnt mean i cnt ansa sm questn..lol,dnt try me o,buh wen talkn of math,chem nd phy,wow count md in.gud9t

ugonna1054: Right!! Wah of no 2??

it dpend on gases u usd,NH3 u av blue,wt HCl u av red..lobatan

ugonna1054: name d gases pls?

wat abt so2

ugonna1054: name d gases pls?

oga me na only amonia nd HCl mostly usd,because they are both soluble in water

Mr Calculus: U GUYS SHOULD POST PRACTICAL QUES LIKE CALCULATIONS CAUSE THEORYTICAL QUES CAN EASILY B BROWSED.
where are all d chemist and physikis

wow..i love ur courage,take dis one.
Solvay process is d name of an industrial process dat mks use of large quantities of salt.what is made in d process

Mr Calculus: do dis sir::
find x if 8^x=4x.

lets mk deal,i solvd urz nd u dnt solv mine,meanin am ur boss,buh u solv mine nd i dnt solv urz,meaning u are ma boss.do we av a deal*stretchn ma hand 4ward tn recieve a handshake*

Mr Calculus: there is no two ways about it.
if (x/2)^x=16.
dat is f(x)=(x/2)^x-16=0.
wit dis it is more like a polynomial in which will substitute values 4 x so dat it will b equal to zero.
and d only value is 4 and dat makes it d answer.
*DAZ ALL*

u wrng dude,i knw d answer is 4,buh i nid a soltn,nd wat if i produce d solutn,u accept am ur boss here.do we av a deal
