To do this, we can use logarithmic differentiation.</p><p>1. Take the natural logarithm of both sides:
\(
\ln y = \ln(x^x) = x \ln x
\)</p><p>2. Differentiate both sides with respect to \( x \):
\(
\frac{1}{y} \frac{dy}{dx} = \ln x + 1
\)</p><p>3. Multiply through by \( y \):
\(
y' = y(\ln x + 1) = x^x(\ln x + 1)
\)</p><p><strong>Step 2: Find \( y'(2) \)</strong></p><p>Now we substitute \( x = 2 \):
\(
y'(2) = 2^2(\ln 2 + 1) = 4(\ln 2 + 1)
\)</p><p><strong>Step 3: Find \( y''(x) \)</strong></p><p>Next, we differentiate \( y'(x) \) to find \( y''(x) \). We will use the product rule:
\(
y' = x^x(\ln x + 1)
\)</p><p>Using the product rule:
\(
y'' = \frac{d}{dx}(x^x) \cdot (\ln x + 1) + x^x \cdot \frac{d}{dx}(\ln x + 1)
\)</p><p>We already found \( \frac{d}{dx}(x^x) = x^x(\ln x + 1) \), and:
\(
\frac{d}{dx}(\ln x + 1) = \frac{1}{x}
\)</p><p>Thus:
\(
y'' = x^x(\ln x + 1)(\ln x + 1) + x^x \cdot \frac{1}{x}
\)
\(
= x^x(\ln x + 1)^2 + x^{x-1}
\)</p><p><strong>Step 4: Find \( y''(2) \)</strong></p><p>Now we substitute \( x = 2 \):
\(
y''(2) = 2^2(\ln 2 + 1)^2 + 2^{2-1} = 4(\ln 2 + 1)^2 + 2
\)</p><p><strong>Step 5: Calculate \( y''(2) - 2y'(2) \)</strong></p><p>Now we can calculate:
\(
y''(2) - 2y'(2) = (4(\ln 2 + 1)^2 + 2) - 2(4(\ln 2 + 1))
\)
\(
= 4(\ln 2 + 1)^2 + 2 - 8(\ln 2 + 1)
\)</p><p><strong>Step 6: Simplify the expression</strong></p><p>Let’s simplify:
\(
= 4(\ln 2 + 1)^2 - 8(\ln 2 + 1) + 2
\)</p><p>This is a quadratic in terms of \( \ln 2 + 1 \):
Let \( u = \ln 2 + 1 \):
\(
= 4u^2 - 8u + 2
\)</p><p><strong>Step 7: Factor or use the quadratic formula</strong></p><p>We can use the quadratic formula:
\(
= 4(u^2 - 2u + \frac{1}{2}) = 4\left((u - 1)^2 - \frac{1}{2}\right)
\)</p><p><strong>Final Result</strong></p><p>Thus, the final answer is:
\(
y''(2) - 2y'(2) = 4\left((\ln 2 + 1 - 1)^2 - \frac{1}{2}\right) = 4\left((\ln 2)^2 - \frac{1}{2}\right)
