Question
√( (664+ √(136+ √(59+ √(21+
√(7+ √81) ) ) ) ) ) = ? What value should come in place of the question-mark(?) in the following questions:Solution
√((664+ √(136+ √(59+ √(21+ √(7+ √81)))))) = √((664+ √(136+ √(59+ √(21+ √(7+ 9)))))) = √((664+ √(136+ √(59+ √(21+ √16))))) = √((664+ √(136+ √(59+ √(21+ 4))))) = √((664+ √(136+ √(59+ √25)))) = √((664+ √(136+ √(59+ 5)))) = √((664+ √(136+ √64))) = √((664+ √(136+ 8))) = √((664+ √144)) = √((664+ 12)) = √676 = 26
