90th - the log

Yesterday we had maths quiz, chemistry replacement, and econs quiz with replacement. ya it was pack. but i survived :D

i just remembered this when we were in economics lesson;
after the 20 mins quiz, we started the new topic which was the economic development. until this part, we got some calculations to do. it was formulae to calculate index as the indicator to measure development. the first 2 parts were simple. just basic maths. but the last part was unusual, at least it didnt come with any explaination as to why it needs log inside. you see here :

Income index = ( lg x - lg 100 ) / ( lg 40000 - lg 100 )

and then timah went; "
owh rupa2 nya ada jugak function kita belajar log selama ni ye. ingatkan xda"
