Answer:
20.08553692319
Step-by-step explanation:
We want to find the value of

Recall that
is the base of the natural logarithm.
You can find this on your scientific calculator as a secondary function;
Enter
on your scientific calculator and press the equal to sign.
You should see the result;
20.08553692319


10x−28=3x+56
10x=3x+56+28
10x=3x+84
10x−3x=84
7x=84

x=12
Hope this helps, have a blessed and wonderful day!

Explanation:
By definition, 
Squaring both sides gets us 
Then multiply both sides by i to get 
Repeat the last step and you should get 
---------------
Notice we have this pattern going on:

Once we reach i^4, we start the process over again.
It repeats every 4 terms.
This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.
157/4 = 39 remainder 1
That remainder 1 is the exponent of the simplified term

---------------
Similarly,
315/4 = 78 remainder 3
So 
---------------
102/4 = 25 remainder 2

----------------
76/4 = 19 remainder 0

Call x as the number of months that Marc and Corinna have the same number of book.
45 +4x= 61 +2x
4x- 2x= 61-45
2x= 16
x= 8
