Good job brother!

9^(x-1)=36 x-1=log36/log9 x-1=1+log4/log9 x=2+2log2/2log3 x=2+log2/log3

Nice

[@alexchan4226]

ln36/ln9 +1

[@0902-u6x]

9 =3^2 and 36=6^2 then the equation same to 3^(x-1)=6 So x= 1+log3 6 = 2 + log3 2

👍

Name the pen you used here sir.

[@SMdE]

x=(ln36/ln9)+1

[@AlexanderSemashkevich]

x=log324/log9=(4log3+2log2)/2log3=2+log2/log3 x≈2+0.301/0.477≈1255/477≈2.631 9^(2.631-1)≈36.0056

[@hangthuy458]

9^x/9=36 9^x=36×9 log9^x=log6^2×9 X=log6^2/log9+log9/log9 X=2log6/2log3+1 log6/log3+1

[@ronaldnoll3247]

x=2.6309

[@rafaelyorro4466]

X=2+logbase9 of 4

Разве это олимпиада? Это обычное уравнение для среднего школьника!

[@francoisgahirwa4554]

in Germany people speacks german!

[@vulcanjibe]

Ouch que c est fastidieux et laborieux pour une simple équation logarithmique...

[@mengmardiati1345]

Jawabanku sama,cuma caraku lbih singkat
