int x^(1/3)(2+x^(2/3))dx" is equal to

int(dx)/((x^(3)-1)^((2)/(3))x^(2)) is equal to

int sqrt (1 + x ^(2)). x dx = (1)/(3) (1 + x ^(2)) ^((3)/(2)) + c

int (2x ^ (3) + 3x ^ (2) + 4x + 5) / (2x + 1) dx equls to: (A) (x ^ (3)) / (2) + (x ^ (2)) / (2) +3 (x) / (2) + (7) / (4) ln (2x + 1) + C (B) 5 (x ^ (3)) / (2) + 6 (x) / (2) + (7) / (4) ln (2x + 1) + C (C) 3 (x ^ (3)) / (2) + 3 (x ^ (2)) / (2) + (7 ) / (4) ln (2x + 1) + C (D) (x ^ (2)) / (2) + 3 (x) / (2) + (7) / (4) ln (2x + 1) + C

int (3x^3+2x^2+3x+1)/(3(x^2+1)) dx=

The value of int_0^1(2x^3-3x^2-x+1)^(1/3)dx is equal to

int(3x^(2)+1)/((x^(2)-1)^(3))dx

int(dx)/(sqrt(x)+sqrt(x-2))= , (A) (1)/(3)[x^(3/2)-(x-2)^(3/2)]+c , (B) (2)/(3)[x^(3/2)-(x-2)^(3/2)]+c , (C) (1)/(3)[(x-2)^(3/2)-x^(3/2)]+c , (D) (2)/(3)[(x-2)^(3/2)-x^(3/2)]+c
