A core concept in "The Complete GMAT Arithmetic & Number Properties Course 2026" is the efficient manipulation of exponents. If $x^{a/b} = \sqrt[b]{x^a}$, and we are given $8^{2/3}$, which of the following represents the correct calculation and result?
tests the fundamental understanding of fractional exponents, a key topic in the GMAT Arithmetic & Number Properties course. The rule $x^{a/b} = (\sqrt[b]{x})^a$ is crucial. In this case, $x=8$, $a=2$, and $b=3$. Applying the rule, we get $8^{2/3} = (\sqrt[3]{8})^2$. The cube root of 8 is 2, since $2 \times 2 \times 2 = 8$. Therefore, $(\sqrt[3]{8})^2 = 2^2 = 4$. Option A correctly applies this rule and arrives at the correct answer. Option B incorrectly interprets the fractional exponent, calculating $\sqrt[3]{8^2}$ which is equivalent to $8^{2/3}$ but leads to a more complex calculation and an incorrect result in this specific application of the rule. Option C and D demonstrate a misunderstanding of exponentiation, treating the exponent as a multiplier or a divisor, which is fundamentally incorrect. Question: "The Complete GMAT Arithmetic & Number Properties Course 2026" emphasizes the distinction between prime and composite numbers. Which of the following statements is *always* true regarding the prime factorization of any integer greater than 1?
