The correct Answer is:
To solve the equation \(\frac{\sqrt[3]{a^8}}{\sqrt{a^3}} = a^x\), we will simplify the left-hand side step by step and find the value of \(x\). ### Step 1: Rewrite the roots in exponent form The cube root of \(a^8\) can be expressed as: \[ \sqrt[3]{a^8} = a^{\frac{8}{3}} \] The square root of \(a^3\) can be expressed as: \[ \sqrt{a^3} = a^{\frac{3}{2}} \] ### Step 2: Substitute the exponent forms into the equation Now we can rewrite the equation: \[ \frac{a^{\frac{8}{3}}}{a^{\frac{3}{2}}} = a^x \] ### Step 3: Apply the property of exponents Using the property of exponents \(\frac{a^m}{a^n} = a^{m-n}\), we can simplify the left-hand side: \[ a^{\frac{8}{3} - \frac{3}{2}} = a^x \] ### Step 4: Find a common denominator To subtract \(\frac{8}{3}\) and \(\frac{3}{2}\), we need a common denominator. The least common multiple of 3 and 2 is 6. We can convert both fractions: \[ \frac{8}{3} = \frac{16}{6} \quad \text{(multiply numerator and denominator by 2)} \] \[ \frac{3}{2} = \frac{9}{6} \quad \text{(multiply numerator and denominator by 3)} \] ### Step 5: Subtract the fractions Now we can perform the subtraction: \[ \frac{16}{6} - \frac{9}{6} = \frac{16 - 9}{6} = \frac{7}{6} \] ### Step 6: Set the exponents equal Now we have: \[ a^{\frac{7}{6}} = a^x \] Since the bases are the same, we can set the exponents equal to each other: \[ x = \frac{7}{6} \] ### Final Answer Thus, the value of \(x\) is: \[ \boxed{\frac{7}{6}} \]
