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

Ikemsinachi: 0

eeya*slap ma face*i no calculate am wella.thanks bro

Odilop: Wat are d types of isomerism in complex ion?

let me say optical or geometry

Odilop: a moxture of thermophile and acidophile !

am confusd,brk it down boss

Ikemsinachi: When is enthalpy change positive for exothermic reaction?

sowie does enthalpy change positive 4 exothermic or endothermic.i tot wen we av positive it is wen d rxt is grta dan product 4 exo,yl postv is wen product grta dan rxt 4 endo,xo i dnt knw d one u talkn abt,ma kemistry ticha no tell me exo na positv o

ok.....I missed smth in NO one and I got 1/2.
NO 2:
Soln;
(x/2)^x = 16
Removing the bracket
x2/2^x = 16
x2/2^x = 16/2^0
=>x = 4( since the x is equals power zero at d denominator; which means 1) dats all. I carefully solved dis one. Hope am correct? NB: x2 means x^2.

,catch u later,abeg mk u na post sm questn here b4 i cm bak.hey dnt tink am xo prd buh dat d way i talk

no u wrng,wat u jst did nw is u repeat bk d same dat put down,4 is d ansa,buh nid workns nt ansa.u cn gv it a try again.i love ur courage.thank u

No be me open thread so I don't know the rules....
But I don't think insults should be allowed here. Don't get me wrong oh..its fun to watch and all but come on.....
Just take it easy with the name calling. U can be angry that's allowed but no name calling pls.

There's a special case wn it is positive

Enthalpy is positive for endothermic reactions...or have I missed sth?
Lemme read thru....

wch type of speciation is associated with the founders effects

Elliotwiz1: don't raise a dead child!! The fact that you knew about that platlet stuff from a website doesn't mean everyone did the same thing, You're just too pugnacious and arrogant I'll say again, if i had gone to that website do you think i would have asked those questions i asked?? Like i said before, the fact that you ask questions and give answers by surfing the web doesn't mean everyone does the same thing, you have no proof that i looked into that website and i hate it when you bring up STUP ID arguments!! We're not kids here!!

bro abeg calm down.. Dnt argue na.. Pls let peace reign

@suave.. Pls let peace reign

Elliotwiz1: i just read all your messages.... you just played a mind game, i'm impressed, but i'm shocked that a dude laughed and he was here from the beginning, Amazed# only a mis-informed person will read that message and not know it was a rhetoric made against me (you understand what i mean) .....i would love to see the screenshot, please post it here....because i know you can fake a message, but you can't clone my username....

bros pls let go..

Dnt derail d thread pls

peternonso: wch type of speciation is associated with the founders effects

Lord of mercy and compassion! Hahahaha! Under which science topic is dis wan? Kai....

peternonso: wch type of speciation is associated with the founders effects

i dnt understand this question

it z nt only u dat z confused o

I_am_Sylva:
aunty storm abeg help me tell them oo

Hahahaha everything is cool....

As for those questions...mehn...only google can help me. As in I have never heard of speciation or founders effect...abi is it physics? Na wa o

STORM2: Enthalpy is positive for endothermic reactions...or have I missed sth?
Lemme read thru....

during heat of combustion and chemical bonds, the energy changes in chemical rxns come frm d breaking of bond(endothermic) and forming of bond(exothermic). But what proceeds the rxn is exothermic.
Exothermic is +ve wn Bond-breaking energies are greater than the bond-forming energies!
That's the only place enthalpy change is +ve for exothermic, if not it is always -ve.

peternonso: wch type of speciation is associated with the founders effects

mutualism........association of ferns and lichen! Hahahahahahaha LWKMD

What's the name of the enzyme secreted by the kidney That's responsible for stimulating the hormone that causes the constriction of the arteries?

Ikemsinachi: There's a special case wn it is positive

u no mean am,ok cnt waite to learn new tin 4rm enthalpy,wat d ansa

hahaha..dnt even undstand d point of dat questn

peternonso: wch type of speciation is associated with the founders effects

oga me are u forming questn 4 here,no one get to knw wat u mean o,abeg recaptulate wt a a gud meanin

peternonso: wch type of speciation is associated with the founders effects

confused o#me know that founders effect comes from isolated species, but me no know name of the specialization.

gv us a chemicl rxt as an example
