The correct Answer is:
To solve the equation \(\frac{\sqrt{x^3}}{x^2} = x^n\) for \(n\), we can follow these steps: ### Step 1: Rewrite the square root The square root of \(x^3\) can be expressed using exponent notation: \[ \sqrt{x^3} = x^{3/2} \] ### Step 2: Substitute into the equation Now, substitute this back into the equation: \[ \frac{x^{3/2}}{x^2} = x^n \] ### Step 3: Simplify the left side When dividing powers with the same base, we subtract the exponents: \[ \frac{x^{3/2}}{x^2} = x^{3/2 - 2} \] ### Step 4: Calculate the exponent Now, calculate \(3/2 - 2\): \[ 3/2 - 2 = 3/2 - 4/2 = -1/2 \] So, we have: \[ x^{-1/2} = x^n \] ### Step 5: Compare exponents Since the bases are the same, we can set the exponents equal to each other: \[ n = -\frac{1}{2} \] ### Final Answer Thus, the value of \(n\) is: \[ \boxed{-\frac{1}{2}} \]
