3.4e^(2-2n)-9=-4

3.4e^(2-2n) = 5

e^(2-2n) = 5/3.4 = 50/34 = 25/17

e^(2-2n) = 25/17

ln both sides

ln( e^(2-2n) ) = ln (25/17)

(2-2n) lne = ln25 - ln17 , but lne = 1

2-2n = ln25-ln17

notice I have yet to touch a calculator ....

-2n = ln25 - ln17 - 2

n= (-1/2)ln25 + (1/2)ln17 + 1 , now to the calculator....

= appr .8072
