Question 12: ∫ x³+ 3x + 4/√x dx

Class 12 - Math - Integrals

Answer 1

I = ∫ x³+ 3x + 4/√x dx

= ∫ x³ dx +3∫x dx +4∫ x^-1/2 dx
= x⁴/4 + 3x²/2 + 8√x + C

Answer 2

heya..!

we can easily integrate it by the use of following two rules :-

(1) integration of
${a}^{n} = \frac{ {a}^{n + 1} }{n + 1}$

(2) integration of a + b + c =
integration of a + integration of b.........
