1. 2^2*-1 = 4

    2^2*-1 = 2^2

    2x-1 = 2

    x = 3/2

    

2. 2x-1√3x-3 = √27

    x-3/3^2x-1 = 3 3/2

    x-3/2x-1 = 3/2

3. 2^1-x^2 = 1/8

    2^1-x^2 = 2^-3

    1-x^2=3; x^2 = 4

    x = +| - 2

4. 3√8x = 65536

    (2^3) x/3 = 2^16

    X = 16

5. 4x^2-6x = 16384

    2^2(x^2-6x) = 2^14

    2x^2-12x = 14
