(1.) dx
here is the problem
= -5x + C integrate
(2.) ∫ a dx here is the problem
= ax + C integrate
(3.) ∫
10x dx here is the problem
= 5x2 + C integrate
(4.) ∫(ax
+ b) dx here is the problem
= (1/2)ax2 + bx + C integrate
(5.) ∫(1
+ 2x + 3x2 + 4x3)dx
here is the problem
= x + x2 + x3 +
x4 + C integrate
(6.) ∫(1
- x + x2 - x3 + x4)dx here is the problem
= x - (1/2)x2 + (1/3)x3
- (1/4)x4 + (1/5)x5 + C integrate
(7.) ∫x-5
dx here is the problem
= (-1/4)x-4 + C integrate
(8.) ∫(12/x3)dx here is the problem
= ∫12x-3
dx use a negative exponent
= -6x-2 + C integrate
(9.) ∫7x-1/2
dx here is the problem
= 14x1/2 + C integrate
(10.) ∫[√x
+ (1/√x)]dx here is the problem
= ∫[x1/2
+ x-1/2]dx use exponents for radical signs
= (2/3)x3/2 + 2x1/2
+ C integrate
