    (3/5)^x should be expressed as [(3/5)*(2kπi)]^x where k is an integer. Then we can get a more general solution. Without putting k, the solution is the specific case when k = 1.

      I tried this and the resulting x is not a solution to the equation. You get x = i PI /( ln(3/5) + 2 PI i k ) (the numerator comes from RHS where ln(-1) = i PI.
      x is a solution for k = 0, but is not a solution for all other values of k.

      Should be [(3/5)*exp(2kπi)]^x , I forgot to type exp()

      @@82rah I typed wrongly, it should be [(3/5)*exp(2kπi)]^x
      1 = exp(2kπi)

      @@82rah the solution in the video put (3/5)^x = [(3/5)*exp(2πi)]^x which is the case when k = 1. If the solution is correct only when k = 0, then the suggested solution in this video when k = 1 is not correct too.

    2:26 - why did you add here e^(2pi * i)? Without adding this I get the answer x=(i*pi)(1+2n)/(ln5-ln3), n is integer.

    • @82rah
      @82rah 10 місяців тому +1

      I agree. x=(i*pi)(1+2n)/(ln5-ln3) is the solution. Adding the e^(2pi * i) on LHS leads to an x that is not a solution. I do not understand why this is.

      I agree. That was a mistake

    I think you left out a multiple of pi in the imaginary part of the solution.

  • @82rah
    @82rah 10 місяців тому +3

    This is not correct. Calculate x for n=0 get x = .496717 - .0128544 i then 3^x + 5^x = 3.949502 - .0703846 i This arises from the exp (2 PI i ) on the LHS. w/o this the solution is x = i PI ( 2 n + 1 )/(ln(5/3) for n= 0 x =6.140029 i 3^x + 5^x = 0 x is soln for other n: if x = -3 x = =30.750147 i and again 3^x + 5^x = 0

    Nonono x is pure imaginary! x=(2n-1) i pi /(ln 5 - ln 3)

    Great video anyway!
