Simplify the expression: (6x^3/3x^4)^2 I worked it out and got 2x^6/x^8 but I am not sure that it is right.

    let's focus on what's inside the parentheses first, and get to the exponent later. |dw:1443996900370:dw| the easiest step is to divide 6/3 = 2, with me so far?

    now let's use the exponent rule to simplify the x's when we divide two numbers with the same base, subtract the exponents like so: (x^3)/(x^4) = x^(-1)

    So would it be 4/x^2
