    another way to eliminate complexity is: x^4 - 2x^2 +1 - 2x^3 + 2x - 0 ( x^2 - 1 )^2 - 2x ( x^2 - 1 ) = 0 ( x^2 - 1 ). ( x^2 - 2x - 1 ) = 0 x^2 - 1 = 0 ==> x = ± 1 or ( x^2 - 2x - 1 ) = 0 x = 1 ± √2

    G.K Mathematics Tricks mistake is that he is assuming that e^(i 2k π) = 3 for k= 1,2,3... is true. It is not. 1^(-(ln(3i)/(2π)) = 1 not 3

      If you have a simple, 4-function calculator that lacks memory or parentheses, and you remember the basic log values, do this: x = 2 + log(10/2)/log(3) = 2 + (1 - log(2))/log(3) ≈ 2 + (1 - .30103)/.47712 ≈ 3.464977...

    Just by looking the problem it is clear that (x-2)!=9! as 8.7.6!=8! and 3!=6. Therefore x-2=9 --> x=11

  • @andrewclifton9772
    @andrewclifton9772 3 หลายเดือนก่อน

    Posted without seeing the solution. x = 11. You should see immediately that 6! x 7 x 8 = 8!. and 3! = 6.So the 8! and 3! in the numerator cancel out with the denominator. You are left with (x-2)!=9!, so x-2 = 9 and thus x=11.
