(√b/√a-√b+√a/√a+√b) *(a/b+b/a-2)

Найдем значение выражения:

(√b/(√a - √b) + √a/(√a + √b))  * (a/b + b/(a - b)); 

(√b * (√a + √b) + √a * (√a - √b))/((√a - √b) * (√a + √b)) * (a/b + b/(a - b)); 

(√b * (√a + √b) + √a * (√a - √b))/(a - b) * (a/b + b/(a - b)); 

(√b * √a + √b * √ + √a * √a - √a * √b))/(a - b) * (a/b + b/(a - b));  

(√b * √b + √a * √a))/(a - b) * (a/b + b/(a - b));  

(√b * √b  + √a * √a))/(a - b) * ()/(a * (a - 2) + b * a)/(b * (a - b));

(a + b)/(a - b) * (a * (a - b) + b * a)/(b * (a - b)); 

(a + b)/(a - b) * (a ^ 2 - a * b + b * a)/(b * (a - b)); 

(a + b)/(a - b) * a ^ 2/(b * (a - b)); 

a ^ 2 * (a + b)/(b * (a ^ 2 - b ^ 2)).
