Question

$\int\limits^2_1 {x^4} \, dx =?$

Answer 1

Answer:

31/5 is the ans

Explanation:

as we have to integrate and substitute the upper and lower limits

Answer 2

Answer:

$\int\limits^2_1 {x^{4} } \, dx=\frac{31}{5}$

Explanation:

$\int\limits^2_1 {x^{4} } \, dx$ =  $\left[\begin{array}{ccc}\frac{x^{5} }{5} \end{array}\right] ^{2} _{1}$         [Integrating $xdx$]

           =  $\frac{2^{5} }{5} - \frac{2^{1} }{5}$         [Limiting from 1 to 2]

           = $\frac{32-1}{5}$ = $\frac{31}{5}$
