Jibu ni 100 ila kwa njia ya Trial&Error... Chora table, row ya kwanza 2logx, table ya pili x/25 then kwenye column anza kutumia akili ya kuzaliwa unajaza numbers hadi upate same soln... kwa sasa sina njia nyingine..... Mzumbe High School PCM

dogo hizo MT ulizosoma hapo coet ndo unaona umesoma kila kitu.course zenyewe sijui kama zinazidi nne halafu ni MT for non major.sijui kama umesoma course ya analysis hata moja dio maana unasema hivi.

I am back now!!

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 &#8730; both sides(but &#8730; means power 1/2)
so, from &#8730;10[SUP](1/25) [/SUP]=&#8730;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
