namaskar dosto aaj ham baat karenge logarith ke baare mein
kyunki CBSE mein syllabus jo hai
usme first year tak logarithm nahi padhaya jaata hai
but 11th mein applications hai kuch log ke to students ko kaafi
dikkate hoti hai log samajhne mein
to aaj ham log ki kuchh basic property
samjhenge
chaliye suru
to logarithm ek function hai
kisi bhi variable ka function logarithm liya ja sakta hai
maan lijiye variable thi m*n
 
iska hamne le liya log
to ye function hame log m
plus log n dega
matlab in dono varibles ka alag alag logs ka sum
jo hoga wo is poore function ke equal hoga
