Question

$log subscript 2 end subscript invisible function application x plus log subscript 2 end subscript invisible function application y greater or equal than 6 comma$ then the least value of $x plus y$ is

4
8
16
32

The correct answer is: 16

$G i v e n log subscript 2 end subscript invisible function application x plus log subscript 2 end subscript invisible function application y greater or equal than 6 rightwards double arrow log subscript 2 end subscript invisible function application open parentheses x y close parentheses greater or equal than 6 rightwards double arrow x y greater or equal than 64$
Also to define $log subscript 2 end subscript invisible function application x blank a n d blank log subscript 2 end subscript invisible function application y comma blank w e blank h a v e blank x greater than 0 comma blank y greater than 0.$
Since $A. M. greater or equal than G. M.$
$therefore fraction numerator x plus y over denominator 2 end fraction greater or equal than square root of x y end root rightwards double arrow x plus y greater or equal than 2 square root of x y end root greater or equal than 16$
