Answer 1

HELLO DEAR,



GIVEN:-
$\bold{\int\limits^3_1(2x^2 + 7)\,dx}$

$\bold{\int\limits^3_1(2x^2\,dx + 7\,dx)}$

$\bold{[2x^3/3 + 7x]^3_1}$

$\bold{[2(3)^3/3 + 7(3) - 2(1)^3/3 - 7(1)]}$

$\bold{18 + 21 - 2/3 - 7}$

$\bold{32 - 2/3}$

$\bold{(96 - 2)/3}$

$\bold{94/3}$


I HOPE ITS HELP YOU DEAR,
THANKS
