Step-by-step EXPLANATION:

How to solve for exponents

  1. xn=y. TAKE the log of both sides:
  2. logxn=logy. By identity we get:
  3. n⋅logx=logy. DIVIDING both sides by log x: n=logylogx. Find the exponent of a NUMBER. ...
  4. 3n=81. Take the log of both sides:
  5. log3n=log81. By identity we get:
  6. n⋅log3=log81. Dividing both sides by log 3: n=log81log3.
