Answer:


\frac{12q^{(7)/(3)}}{p^(3)}

Explanation:

Here are some rules you need to simplify this expression:

Distribute exponents: When you raise an exponent to another exponent, you multiply the exponents together. This includes exponents that are fractions.
(a^(x))^(n) = a^(xn)

Negative exponent rule: When an exponent is negative, you can make it positive by making the base a fraction. When the number is apart of a bigger fraction, you can move it to the other side (top/bottom).
a^(-x) = (1)/(a^(x)), and to help with this question:
(a^(-x)b)/(1) = (b)/(a^(x)).

Multiplying exponents with same base: When exponential numbers have the same base, you can combine them by adding their exponents together.
(a^(x))(a^(y)) = a^(x+y)

Dividing exponents with same base: When exponential numbers have the same base, you can combine them by subtracting the exponents.
(a^(x))/(a^(y)) = a^(x-y)

Fractional exponents as a radical: When a number has an exponent that is a fraction, the numerator can remain the exponent, and the denominator becomes the index (example, index here ∛ is 3).
a^{(m)/(n)} = \sqrt[n]{a^(m)} = (\sqrt[n]{a})^(m)


((8p^(-6) q^(3))^(2/3))/((27p^(3)q)^(-1/3)) Distribute exponent


=(8^((2/3))p^((-6*2/3))q^((3*2/3)))/(27^((-1/3))p^((3*-1/3))q^((-1/3))) Simplify each exponent by multiplying


=(8^((2/3))p^((-4))q^((2)))/(27^((-1/3))p^((-1))q^((-1/3))) Negative exponent rule


=(8^((2/3))q^((2))27^((1/3))p^((1))q^((1/3)))/(p^((4))) Combine the like terms in the numerator with the base "q"


=(8^((2/3))27^((1/3))p^((1))q^((2))q^((1/3)))/(p^((4))) Rearranged for you to see the like terms


=(8^((2/3))27^((1/3))p^((1))q^((2)+(1/3)))/(p^((4))) Multiplying exponents with same base


=(8^((2/3))27^((1/3))p^((1))q^((7/3)))/(p^((4))) 2 + 1/3 = 7/3


=\frac{\sqrt[3]{8^(2)}\sqrt[3]{27}p\sqrt[3]{q^(7)}}{p^(4)} Fractional exponents as radical form


=\frac{(\sqrt[3]{64})(3)(p)(q^{(7)/(3)})}{p^(4)} Simplified cubes. Wrote brackets to lessen confusion. Notice the radical of a variable can't be simplified.


=\frac{(4)(3)(p)(q^{(7)/(3)})}{p^(4)} Multiply 4 and 3


=\frac{12pq^{(7)/(3)}}{p^(4)} Dividing exponents with same base


=12p^((1-4))q^{(7)/(3)} Subtract the exponent of 'p'


=12p^((-3))q^{(7)/(3)} Negative exponent rule


=\frac{12q^{(7)/(3)}}{p^(3)} Final answer

Here is a version in pen if the steps are hard to see.
