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
