    Here are some rules to remember:

    x^y * x^z means x^(y+z). Add the exponents.

    x^y / x^z means x^(y-z). Subtract the exponents.

    (x^y)^z means x^(y*z). Multiply the exponents.

    x^-y means 1/(x^y). Place the number below 1 and make the exponent positive.

    x^(y/z) means the z root of x^y.

    (x^8 / x^6)^-4

    Subtract the exponents inside the parenthesis:

    (x^(8-6))^-4

    (x^2)^-4

    Multiply the exponents:

    x^(2(-4))

    x^-8

    Make the exponent positive:

    1/(x^8)

    Answer: 1 / x^8

    isElementOfR(X)=true;

    X != 0;

    (X^8 / X^6)^-4 = (X^2)^-4 = X^-6= 1/X^6
