Understanding Fractional Exponents
Fractional exponents are a way to express powers and roots together. An expression like \(a^{\frac{m}{n}}\) represents taking the nth root of \(a\) and then raising it to the power of \(m\).
- \(a^{\frac{m}{n}} = \sqrt[n]{a^m} = (\sqrt[n]{a})^m\)
- Here, \(a\) is the base, \(m\) is the numerator, and \(n\) is the denominator of the exponent.
- The denominator \(n\) indicates the root to be taken (e.g., \(n=2\) is square root, \(n=3\) is cube root).
- The numerator \(m\) indicates the power to which the base (or the root of the base) is raised.
For example, \(8^{\frac{2}{3}}\) is calculated as follows: First, find the cube root of 8, which is 2 (\(\sqrt[3]{8} = 2\)). Then, square the result: \(2^2 = 4\). So, \(8^{\frac{2}{3}} = 4\).
