8k=360
k=45 may this will help you
how it becomes 8k ?
take 3 to lhs and write it as log8base2
the use basic properties of log
i have made loɡ₂K=2loɡ₂6+loɡ₂10−3 loɡ₂K=loɡ₂6²+loɡ₂10−loɡ₂³
loɡ₂k=loɡ₂36+loɡ₂10−loɡ₂3
= loɡ₂36×10÷3
where is the mistake ?
oh 3 will be written as log8base2
and sorry for being late

log k=log36+log10/3
logk= log 360/3
k= 360/3
k=120
