Solution by Steps
step 1
To simplify the expression (9x)54\sqrt[4]{(9x)^5} in terms of fractional exponents, we first rewrite the fourth root as an exponent
step 2
The fourth root of a number can be written as raising that number to the power of 14\frac{1}{4}. So, (9x)54\sqrt[4]{(9x)^5} becomes ((9x)5)14((9x)^5)^{\frac{1}{4}}
step 3
Next, we use the property of exponents that states (am)n=amn(a^m)^n = a^{m \cdot n}. Applying this property, we get ((9x)5)14=(9x)514((9x)^5)^{\frac{1}{4}} = (9x)^{5 \cdot \frac{1}{4}}
step 4
Simplify the exponent: 514=545 \cdot \frac{1}{4} = \frac{5}{4}. Therefore, (9x)54(9x)^{\frac{5}{4}}
Answer
(9x)54(9x)^{\frac{5}{4}}
Key Concept
Fractional Exponents
Explanation
Fractional exponents are another way to represent roots. The expression (9x)54\sqrt[4]{(9x)^5} can be rewritten using the exponent 14\frac{1}{4}, and then simplified using the properties of exponents.
