Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
2^n - 3 = 83 
<span>2^n = 86 </span>
<span>ln(2^n) = ln(86) </span>
<span>n*ln(2) = ln(86) </span>
<span>n= ln(86)/[ln(2)] (which is the same as "log base 2 of 86") </span>

Anyone know inverse operations, cause I am confused, I looked online and it said
bija089 [108]

Answer:

For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.

Inverse operations are also very helpful for linear equations.

To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.

Ex:

13 - 2 = 11    (now change plus to minus)

13 + 2 = 11      (not the answer yet)

Now we switch the first number with the answer!

11 + 2 = 13

Hope this helped, I tried to explain it easily.
