Q. Calculate the integral and write your answer in simplest form.∫254x3dxAnswer:
Rewrite Integral: Rewrite the integral in a more familiar form.The given integral is ∫254x3dx. The fourth root of x3 can be written as x3/4, so the integral becomes ∫25x3/4dx.
Simplify Coefficients: Simplify the constant coefficients.We can factor out the constant from the integral to simplify the expression. This gives us 25∫x3/4dx.
Apply Power Rule: Apply the power rule for integration.The power rule states that ∫xndx=n+1xn+1+C, where C is the constant of integration. Applying this rule to our integral, we get 25⋅3/4+1x3/4+1+C.
Simplify Exponent and Fraction: Simplify the exponent and the fraction.Adding 1 to 3/4 gives us 7/4, so the integral becomes 25⋅7/4x7/4+C. To simplify the fraction, we multiply by the reciprocal of 7/4, which is 4/7.
Multiply Constants: Multiply the constants and write the final answer.Multiplying 25 by 4/7 gives us 2⋅75⋅4=1420, which simplifies to 710. Therefore, the final answer is 710x7/4+C.
