Given : The Total Bill at the Restaurant is $84.99
Given : The Additional Tax is $5.10
⇒ Total Bill Including the Tax is : (84.99 + 5.10) = $90.09
Given : Three Friends decide to evenly split their Bill
⇒ $90.09 should be Divided into 3 Equal Parts
![\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = (\frac{90.09}{3})}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Cimplies%20The%5C%3BAmount%5C%3Beach%5C%3Bperson%5C%3Bshould%5C%3Bowe%5C%3Bis%20%3D%20%28%5Cfrac%7B90.09%7D%7B3%7D%29%7D)
![\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = 30.03\;Dollars}](https://tex.z-dn.net/?f=%5Cmathsf%7B%5Cimplies%20The%5C%3BAmount%5C%3Beach%5C%3Bperson%5C%3Bshould%5C%3Bowe%5C%3Bis%20%3D%2030.03%5C%3BDollars%7D)
His Friend Calculation is <u>not</u> Reasonable
I= sqrt (-1)
If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i
99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd
Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i
But what is the expression, you have to tell me so I can do it.
