    x^(3/2) =27

    x = 27^(2/3) + (27^2)^(1/3) = 729^(1/3) = 9

    x = 27^(2/3) + (27^(1/3))^2 = 3^2 = 9

    A fractional exponent is equivalent to a root: x^(1/2) = sqrt(x); x^(1/y) = yrt(x).

    X^3/2 = 27

    (x^3/2)^2/3=27^2/3

    x= cubed root of 27 squared

    x= 3 squared

    x=9

    x^3/2 means x times its square root so since 9*3=27 x=9

    x^3/2 = 27

    =

    (√x)³ = 27

    Find the cube root on both sides

    √x = 3

    Square both sides

    x = 9

    x^(3/2) = 27

    √x^3 = 27

    (√x^3)^2 = 27^2

    x^3 = 729

    x = ³√729

    x = 9

    Easy.

    (X^3/2)*2=27*2

    X^3=54

    Cubed root of X^3=cubed root of 54

    Roughly 3.78
