Could anyone explain to me what "Base e" is?

see below :)

Step-by-step explanation:

This is a little complicated but base e which means Euler's number is usually used when solving logarithms. base e equals to 2.71828. You can kind of compare this to pi. This is an irrational number and usually is used in natural logs. I hope this helps.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
