int_(0)^(a)(sqrt(x))/(sqrt(x)+sqrt(a-x))dx

By using the properties of definite integrals, evaluate the integrals int_(0)^(a)(2sqrt(x))/(sqrt(x)+sqrt(a-x))dx

int_(0)^(a)(sqrtx)/(sqrt(x) + sqrt(a-x))dx .

2. int_(0)^(5)(sqrt(x))/(sqrt(x)+sqrt(5-x))dx

By using the properties of definte, prove that int_(0)^(a)(sqrt(x)dx)/(sqrt(x)+sqrt(a-x))=a/2

int_(0)^(9)sqrt(x)/(sqrt(x)+sqrt(9-x))dx=(9)/(2)

int_(0)^(7)(sqrt(7-x))/(sqrt(x)+sqrt(7-x))dx = (a) 1 (b) (7)/(2) (c) 5 (d) 7

int_(a)^(b)(sqrt(x))/(sqrt(x)+sqrt(a+b-x))dx= . . . .

int_(a)^(b)(sqrt(x))/(sqrt(x)+sqrt(a)+b-x) =dx=......
