Mathematician Kuna kichwa hapa

[Poriposha]

Find the value of x, I need solution please not answer without soln...

2[SUP]x[/SUP]=4x (two power x equal to four x)

Solution plzzzzz is what i prefer!!!

 

[Rejao]

Appy ln or log both sides..

 

[Poriposha]

Appy ln or log both sides..

Fanya nipe sol hapa acha uvivu

 

[Poriposha]

Appy ln or log both sides..

ln nimesahau inakuwa-applied vp??

changia jf..ngoja nikushukie kaswali hako mi ndio newton mwenyewe

changia jf..ngoja nikushukie kaswali hako mi ndio newton mwenyewe

Mi nataka nimuone mjanja!!! porojo hazina nafasi kwenye namba... JITAHIDI MAN

 

[Abdulhalim]

Tulishasolve hili suala. Pekua kwene makabrasha ya JF, wewe ndio uache uvivu.

 

[nyambari]

Introduce log on both sides then .....

Kama matumizi ya hiyo hesabu ni kuwaondoa mafisadi nitaifanya.

Kama matumizi ya hiyo hesabu ni kuwaondoa mafisadi nitaifanya.

Watu wametumia hesabu za high prime numbers kuingiza encryption katika computer na hivyo kuondoa ufisadi katika computer, acha kufikiri kwamba hesabu hazina maana katika maisha. Kama hujui/ huwezi hesabu sema tu.

Utawezaje kufanya accounting na kujua kama pesa zinaibiwa na mafisadi bila kujua hesabu rahisi tu?

Are you serious?

 

[Mkuu wa chuo]

mbona hii tayari ilikwisha fanywa humu na demu mmoja anaitwa Husninyo!

 

[Mzee]

Jarbu kupekua kwenye mafaili utakuta hii mambo ipo solved.

 

[KakaJambazi]

Mtafute chief accountant Husninyo, alishaifanya hii.

 

[Sita Sita]

Hii hesabu ilileta ubishi mwingi sana.

Ukifanya kwa log hautomaliza.

Chora graph ya y=4x na graph ya y=2[SUP]x[/SUP]hapo kwenye intersection ya hizo graph ndo jibu lako.

Husninyo alidanganya kwenye solution yake.

 

[Stany]

Graphical method is the most apropriate appropriate y=2^x then linear eqn y=2x record the intersection points as u answer

Hapa hamna ubishi aisee...but solution yako ipo rough! ungeedit utumie space! au ni mambo ya kukopi na kupesti?
