I am not able to understand why Maple fails to compute and display the integrals for Eqn (1) and Eqn (8). I have a integral table to cross-verify the integrals for each of these in here. 

 

Also, another integral I am trying to calculate in MWE2 (attached file) in which the integral computed doesn't make any sense.

MWE-2.mw

 

> 

int(sqrt(x^3.(ax+b)), x)

int((x^3.(ax+b))^(1/2), x)

 (1)
> 

2+2

4

 (2)
> 

int(7*x^3+3*x^2+5*x, x)

(7/4)*x^4+x^3+(5/2)*x^2

 (3)
> 

int(1, x)

x

 (4)
> 

int(1/(x^2+1), x)

arctan(x)

 (5)
> 

int(1/(ax^2+bx+c), x)

x/(ax^2+bx+c)

 (6)
> 

int(x^n, x)

x^(n+1)/(n+1)

 (7)
> 

int(sqrt(x(ax+b)), x)

int(x(ax+b)^(1/2), x)

 (8)
