Hi, i was wondering how to find 'e' in the exponential trendline equation "8=142.72*e^(-0.512*6)

I'm doing a maths assignment and I have no idea how to find the e value in an exponential trendline equation, especially with a power equation attached

"e" usually represents Euler's constant. Is that the case here?

Your equation, worked out, says
8 = 6.61199
 
Are you sure you typed this correctly?
 
Or is "e" just a variable as opposed to
Euhler's number?

e in this context is OBVIOUSLY the base of the natural logarithms.

On a graphing calculator, you get e by doing SHIFT LN (e.g. Gold key + ln key) and the value is about 2.7182818284
