The value of x² d x x⁶+a⁶ is equal to
Options
- A|x³+ x⁶+a⁶ |+C
- B|x³- x⁶+a⁶ |+C
- C1 3 |x³+ x⁶+a⁶ |+C
- D1 3 |x³- x⁶+a⁶ |+C
Correct answer
C. 1 3 |x³+ x⁶+a⁶ |+C
Step-by-step solution
Let I= x² x⁶+a⁶ d x Let x³=t aligned 3 x² d x &=d t I &= 1 3 1 t²+ (a³ )² d t &= 1 3 |t+ t²+a⁶ |+C &= 1 3 |x³+ x⁶+a⁶ |+C aligned
