ln (1/(e^k))=-7
raise everything to the e power
(1/e^k) = exp(-7)
but that is e^(-k)=e^(-7)
k=7
ln (1/e^7)=-7

ln+%281%2Fe%5Ek%29+=+-+7

ln+%28e%5E%28-+k%29%29+=+-+7 ------ 1%2Fe%5Ek = e%5E%28-+k%29

e%5E%28-+k%29+=+e%5E%28-+7%29 -------- Exponential form

Thus, - k = - 7

k+=+%28-+7%29%2F%28-+1%29, or highlight_green%28k+=+7%29
