After applying the power of a product rule, our expression is now in the form . The next step involves simplifying the term . Here, we encounter another fundamental rule of exponents: the power of a power rule. This rule states that when a term raised to a power is further raised to another power, we multiply the exponents. Mathematically, this is represented as . Applying this rule to our expression, we multiply the exponents 27 and : . This simplification significantly reduces the complexity of our expression. The x term, initially raised to the power of 27 and then to the power of , is now simply x raised to the power of 9. This transformation is a testament to the power of exponent rules in streamlining algebraic expressions. The remaining term, , represents the cube root of y and can be expressed in radical form. Understanding and applying these exponent rules is essential for simplifying a wide range of mathematical expressions.
Converting Fractional Exponents to Radicals
Our expression now stands as . The term is a fractional exponent, and it can be equivalently expressed in radical form. A fractional exponent of the form indicates the nth root of the base. In our case, represents the cube root of y, which is written as . This conversion is a fundamental concept in algebra, bridging the gap between exponents and radicals. By expressing fractional exponents as radicals, we often gain a clearer understanding of the expression's behavior and can perform further simplifications or calculations more easily. In this context, the cube root of y signifies the value that, when multiplied by itself three times, equals y. This transformation allows us to rewrite our expression in a more conventional radical notation, making it easier to compare with the given options. Understanding the relationship between fractional exponents and radicals is crucial for mastering algebraic manipulations and problem-solving.
