mboni inaonekana kama copy and paste hiyo mzee hasa kuanzia hapo kwenye bluu

Kivipi mkuu??
Copy from where?
Au kwakua nimeweka ufafanuzi kwenye kila stage?

2Logx = x/25

Divide by x both sides
(2/X)logx = 1/25

logx [SUP](2/x)[/SUP] = 1/25


Remove log sign
10[SUP](1/25) [/SUP]= x[SUP](2/x)

[/SUP]Take √ both sides(but √ means power 1/2)
so, from √10[SUP](1/25) [/SUP]=√x [SUP](2/x)[/SUP]

we will get
10[SUP]1/25(1/2)[/SUP] = x[SUP]2/x(1/2)

[/SUP]simplify on exponents
10[SUP]1/50[/SUP] =x[SUP]1/x

[/SUP]10[SUP]2/2*1/50[/SUP] =x[SUP]1/x[/SUP] note 2/2=1, so will not change the value of exponent
10[SUP]2(1/100)[/SUP] =x[SUP]1/x

[/SUP]100[SUP]1/100[/SUP] = x [SUP]1/x[/SUP]

x = 100

good broza .sasa huyo wa coet udsm anakuambia hamna njia

I like your approach

nimekubali kaka kwa kuwaumbua coet mwaka wa nne!!
Hawana knowledge ya exponential logarithm!
Tht is the way it suposed to be

wenye akili ndogo kama nyie ndo huwa mnadiscus kwamba katoa wap lkn magreatthinker wanachukua idea na kusema let me try anaza way

 

[Narubongo]

2 log x= x/25
50 log x = x

baada ya hapo ni kupachika namba kulia kushoto na balance inapatikana @ x= 100
50 log 100 = 100
50*2 = 100
100 = 100
since i know X = 100 then solution to suit my answer will be forged as well

if you didn't know x=100
