Take the natural log of both sides and solve.

Explanation:

Note that ln(x) is the natural logarithm or log_e(x).

First, we can take the natural log of both sides to get n out of the exponent:
ln(e^(-3n))=ln(83)

Since the ln and the e cancel, we get:
-3n=ln(83)

Dividing -3 from both sides, we get our value of n as:
n=-ln(83)/3~~-1.473 rounded to three decimal places
