Can these please be solved on paper with a step by step explanation

4. Use multiplication to find the first three nonzero terms of the Maclaurin series for y = e" In(1 + x). 5. Determine the Taylor polynomial of with degree n centered at a and use Taylor's formula to estimate the accuracy of the approximation f(x) ~ T,(a) when a lies in the given interval. a) f(x) = In(1 + 2x) , a = 1, n = 3, 0.5
