1 - √b/1 - √a
√a - √ab = √a - √a x √b = √a(1 - √b)
√b - √ab = √b(1 - √a)
√a(1 - √b)/√b(1 - √a) + 1 - √b/1 - √a
E = ..........................................................
√a(1 - √b)(1 - √a) + √b(1 - √b)(1 - √a)]/√b(1 - √a)²
E = ..............................................................................
(1 - √b)(1 - √a)(√a + √b)/√b(1 - √a)²
E = ............................................................
(1 - √b)(1 - √a)(√a + √b)(1 - √a) (√a + √b)
