If (48)/((2)(3)) + (47)/((3)(4)) + (46)/((4)(5))+ …..(2)/((48) (49)) + (1)/((49)(50))= (51)/(2) + K (1+ (1)/(2)+ (1)/(3) + …+ (1)/(50)) , then K equals

If (sqrt8 +i)^(50) = 3^(49) (a+ib), " then " a^(2)+b^(2) is :

The value of ((50),(0)) ((50),(1)) + ((50), (1)) ((50),(2)) +............+ ((50),(49))((50),(50)) is
