Have the first four answers correct. just need with the last one. consider the integral ? 6x3(x4+1)dx. in the following, we will evaluate the integral using two methods. a. first, rewrite the integral by multiplying out the integrand: ? 6x3(x4+1)dx=? 6x^7+6x^3 dxthen evaluate the resulting integral term-by-term: ? 6x3(x4+1)dx= ((6x^8)/8)+((6x^4)/4)+cb. next, rewrite the integral using the substitution w=x4+1: ? 6x3(x4+1)dx=/4)*w) dwevaluate this integral (and back-substitute for w) to find the value of the original integral: ? 6x3(x4+1)dx= ((3(x^4+1)^2)/4)+cc. how are your expressions from parts (a) and (b) different? what is the difference between the two? (ignore the constant of from from a) =are both of the answers correct? (be sure you can explain why they are! )
