@Sagnik..u didnt mentioned the base of Log..so i took it as 10...that's why the answer is coming 20..
but if u take base e then the answer will be 6...

log(anething) means to the base 10

ln(nething) means to the base e

if base is any oder number then it shud be mentioned

i guess it was ln and sagnik wrote log

can somebody do the q without graph ?
