I need help with 41. I got to a really bad fraction, and was wondering if there's a easier way of doing this. I got (x^4/5 -4x^-1/5)(2x^6/5 + (4/5)(x^4/5)-(16/5)(x^-1/5))

29-48 Find the critical numbers of the function. 29. f(x) - 3x + x - 2 30. g(v) - v - 120 + 31. f(x) = 3x* + 8x3 - 48.x 32. f(x) = 2x + .x3+ 33. g(1) = 15 + 513 + 501 34. A(x) = 13 - 2x/ 35. g(y) = y - 1 36. h(p) = P- 1 32 - y +1 p' + 4 x2 + 2 12 + 9 37. p(x) - 2x - 1 38. q(1) - 12 - 9 39. h(1) = 13/4 - 21 1/4 40. g(x) - V4 -x2 41. F(x) = x4/5(x - 4)2 42. h(x) = x-1/3(x - 2)
