The correct Answer is:
To find the derivative of the function \( G(x) = (\sqrt{2}x^3 + x^5)(\sqrt{3}x^2 + \frac{1}{5}x^5) \), we will use the product rule of differentiation. The product rule states that if you have two functions \( u(x) \) and \( v(x) \), then the derivative of their product is given by: \[ (uv)' = u'v + uv' \] ### Step 1: Identify the functions Let: - \( u(x) = \sqrt{2}x^3 + x^5 \) - \( v(x) = \sqrt{3}x^2 + \frac{1}{5}x^5 \) ### Step 2: Find the derivatives \( u' \) and \( v' \) 1. **Differentiate \( u(x) \)**: \[ u'(x) = \frac{d}{dx}(\sqrt{2}x^3) + \frac{d}{dx}(x^5) = 3\sqrt{2}x^2 + 5x^4 \] 2. **Differentiate \( v(x) \)**: \[ v'(x) = \frac{d}{dx}(\sqrt{3}x^2) + \frac{d}{dx}\left(\frac{1}{5}x^5\right) = 2\sqrt{3}x + x^4 \] ### Step 3: Apply the product rule Now we apply the product rule: \[ G'(x) = u'v + uv' \] Substituting \( u, u', v, \) and \( v' \): \[ G'(x) = (3\sqrt{2}x^2 + 5x^4)(\sqrt{3}x^2 + \frac{1}{5}x^5) + (\sqrt{2}x^3 + x^5)(2\sqrt{3}x + x^4) \] ### Step 4: Expand the expression 1. **First term**: \[ (3\sqrt{2}x^2)(\sqrt{3}x^2) + (3\sqrt{2}x^2)(\frac{1}{5}x^5) + (5x^4)(\sqrt{3}x^2) + (5x^4)(\frac{1}{5}x^5) \] \[ = 3\sqrt{6}x^4 + \frac{3\sqrt{2}}{5}x^7 + 5\sqrt{3}x^6 + x^9 \] 2. **Second term**: \[ (\sqrt{2}x^3)(2\sqrt{3}x) + (\sqrt{2}x^3)(x^4) + (x^5)(2\sqrt{3}x) + (x^5)(x^4) \] \[ = 2\sqrt{6}x^4 + \sqrt{2}x^7 + 2\sqrt{3}x^6 + x^9 \] ### Step 5: Combine like terms Now combine all the terms: \[ G'(x) = (3\sqrt{6} + 2\sqrt{6})x^4 + (5\sqrt{3} + 2\sqrt{3})x^6 + \left(\frac{3\sqrt{2}}{5} + 1\right)x^7 + 2x^9 \] \[ = 5\sqrt{6}x^4 + 7\sqrt{3}x^6 + \left(\frac{3\sqrt{2}}{5} + 1\right)x^7 + 2x^9 \] ### Final Answer Thus, the derivative \( G'(x) \) is: \[ G'(x) = 5\sqrt{6}x^4 + 7\sqrt{3}x^6 + \left(\frac{3\sqrt{2}}{5} + 1\right)x^7 + 2x^9 \]
