Answer

\( a = \frac{7}{6} \)

Solution

To find the value of \( a \) in the equation \[ \frac{x^{2}}{x^{\frac{5}{6}}} = x^{a}, \] we can simplify the left-hand side (LHS) using the properties of exponents. ### Step 1: Simplify the LHS Recall the exponent rule: \[ \frac{x^{m}}{x^{n}} = x^{m - n}. \] Applying this rule to the LHS: \[ \frac{x^{2}}{x^{\frac{5}{6}}} = x^{2 - \frac{5}{6}}. \] ### Step 2: Subtract the Exponents To subtract the exponents, we need to have a common denominator: \[ 2 = \frac{12}{6}. \] So, \[ 2 - \frac{5}{6} = \frac{12}{6} - \frac{5}{6} = \frac{7}{6}. \] ### Step 3: Equate the Exponents Now, the equation becomes: \[ x^{\frac{7}{6}} = x^{a}. \] Since the bases are the same, the exponents must be equal: \[ a = \frac{7}{6}. \] ### Final Answer \[ a = \frac{7}{6}. \]

To simplify the left-hand side of the equation \( \frac{x^{2}}{x^{\frac{5}{6}}} \), we can use the property of exponents that states \( \frac{x^m}{x^n} = x^{m-n} \). So, we have: \[ \frac{x^{2}}{x^{\frac{5}{6}}} = x^{2 - \frac{5}{6}} \] Now, let's convert \( 2 \) into a fraction with a denominator of 6: \[ 2 = \frac{12}{6} \] Thus, we can rewrite the exponent: \[ 2 - \frac{5}{6} = \frac{12}{6} - \frac{5}{6} = \frac{12 - 5}{6} = \frac{7}{6} \] Therefore, the left-hand side simplifies to: \[ x^{\frac{7}{6}} \] Setting this equal to the right-hand side of the equation: \[ x^{\frac{7}{6}} = x^{a} \] Since the bases are the same, we can equate the exponents: \[ a = \frac{7}{6} \] So, the value of \( a \) in the equation is: \[ \frac{7}{6} \]
