Maths expression may at times look challenging, but a bit of a thought may make it otherwise.
Logarithm is always an exciting topics to new learners.
With the "log" coming into the maths expression, one will be confused.
But do rest assure, as the tip below shows.
eln y = y
"Natural log" both sides will give ln eln y = ln y
Applying the law that ln an = n ln a, and that ln e = 1, you will notice that the above mathematical expressions are true and equal.
This tip applies to "log" too.
10log y = y
Hope this helps.
