Jawaban:
2.496
Penjelasan dengan langkah-langkah:
[tex]\displaystyle\rm~\int_{2}^{5}~ {nx}^{2} ~dx = .... ?[/tex]
n = 64
maka,
[tex]\begin{aligned}\displaystyle\rm~\int_{2}^{5}~ {64x}^{2} ~dx & = \displaystyle\rm~ \frac{64}{3} {x}^{3} ~\Bigr|_{2}^{5} \\ \\& = \displaystyle\rm~( \frac{64}{3} {(5)}^{3}) - ( \frac{64}{3} {(2)}^{3}) \\ \\ & = \displaystyle\rm~( \frac{64}{3}(125)) - ( \frac{64}{3}(8)) \\ \\ & = \displaystyle\rm~ \frac{8000}{3} - \frac{512}{3} \\ \\ & = \displaystyle\rm~ \frac{7.488}{3} \\ \\ & = \displaystyle\rm~2.496 \end{aligned}[/tex]
