A) 13(x2+8) 3/2+tan1(x8) +C\frac { 1 } { 3 } \left( x ^ { 2 } + 8 \right) ^ { 3 / 2 } + \tan ^ { - 1 } \left( \frac { x } { 8 } \right) + C
B) 13(x2+8) 3/28x2+8+C\frac { 1 } { 3 } \left( x ^ { 2 } + 8 \right) ^ { 3 / 2 } - 8 \sqrt { x ^ { 2 } + 8 } + C
C) 13x2+88x2+8+C\frac { 1 } { 3 } \sqrt { x ^ { 2 } + 8 } - \frac { 8 } { \sqrt { x ^ { 2 } + 8 } } + C
D) 18(x2+8) 3/2x2+8+C\frac { 1 } { 8 } \left( x ^ { 2 } + 8 \right) ^ { 3 / 2 } - \sqrt { x ^ { 2 } + 8 } + C
