    (x2)3(2x3)3/(4x)2

    I got 1/2x^13, is this correct?

    For clarity use parentheses (1/2)x^13

    Yeah, you've got it.
    Remember that raising a power of ##x## to a power is like multiplying the exponents. So, ##(x^n)^m = x^{nm}##. In the numerator, you've got ##2x^{15}##, while in the denominator, you've got ##4x^2##. The 4 cancels the 2, and by basic exponent laws, the square in the denominator cancels two powers of ##x## in the numerator. So, you get ##\frac{1}{2} x^{13}##, which is what you got.
