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

Hakuna ubishi according to you, ila sisi wajanja tumeshaona hakuna kitu hapo.

Ukiapply naperian number unarejea tena kwene

2^(x-2)==x

Ambayo ni kitu kilekile na swali uliloulizwa

2^x==4x, except umehamishia '4' upande mwengine..
