Q. Calculate the integral and write your answer in simplest form.\newline5x342dx \int \frac{5 \sqrt[4]{x^{3}}}{2} \mathrm{dx} \newlineAnswer:
  1. Rewrite Integral: Rewrite the integral in a more familiar form.\newlineThe given integral is 5x342dx\int \frac{5\sqrt[4]{x^3}}{2} \, dx. The fourth root of x3x^3 can be written as x3/4x^{3/4}, so the integral becomes 5x3/42dx\int \frac{5x^{3/4}}{2} \, dx.
  2. Simplify Coefficients: Simplify the constant coefficients.\newlineWe can factor out the constant from the integral to simplify the expression. This gives us 52x3/4dx\frac{5}{2} \int x^{3/4} \, dx.
  3. Apply Power Rule: Apply the power rule for integration.\newlineThe power rule states that xndx=xn+1n+1+C\int x^n \, dx = \frac{x^{n+1}}{n+1} + C, where CC is the constant of integration. Applying this rule to our integral, we get 52x3/4+13/4+1+C\frac{5}{2} \cdot \frac{x^{3/4 + 1}}{3/4 + 1} + C.
  4. Simplify Exponent and Fraction: Simplify the exponent and the fraction.\newlineAdding 11 to 3/43/4 gives us 7/47/4, so the integral becomes 52x7/47/4+C\frac{5}{2} \cdot \frac{x^{7/4}}{7/4} + C. To simplify the fraction, we multiply by the reciprocal of 7/47/4, which is 4/74/7.
  5. Multiply Constants: Multiply the constants and write the final answer.\newlineMultiplying 52\frac{5}{2} by 4/74/7 gives us 5427=2014\frac{5 \cdot 4}{2 \cdot 7} = \frac{20}{14}, which simplifies to 107\frac{10}{7}. Therefore, the final answer is 107x7/4+C\frac{10}{7}x^{7/4} + C.
