4*log2(|x-1|)=12 -> log2(|x-1|)=3 -> |x-1|=2^3 -> x1=8+1=9 AND x2= -8+1=-7

Jacqueline :

was not it so hard when I was at school? 😳😳😳

Chiara✨ :

È come vedere un ex

sir :

It’s incomplete. This logarithmic equation has two solutions for x: 9 and -7.

Jay4Jay🤏🎮 :

bro 2X3 is 8 seriously 😭

Georgefzx750 :

4log(2)|x-1|=12.......|x-1|=8 x=-7 or x=8

Giovanni Chisari :

I didn’t understand how became 2 alle 3 equal x-1?

Adél 😅😘😇 :

x=9

🗡️🛡️•S4int•🛡️🗡️ :

i’m getting an ick because because why is it sideways😭😭😭

ripmyvidsoidontgetbanedfrmucas :

what about negative

Massimino :

bad work. x-1 Is positive??????

Mukavis ofo :

where has log gone

숬 :

changing the sign x-1 to x+1 since you altered the RHS numbers to the LHS, alternatively it was to be -2³=x-1 then you multiply by _ve both sides

Damian026 :

Not me being mad cos you writr so slowly 😭

Susana De San Luis :

muy mal explicado

@Jerula💙 :

thanks 😉

Jr Cenial :

Thank you very much
