The value of 5 12 12 is

Options

A1
B1 2
C1 4

Correct answer

Step-by-step solution

Given, expression is 5 12 12 . We know that, aligned & 2 A B= (A-B)- (A+B) & Therefore, 5 12 12 & = 1 2 [ ( 5 12 - 12 )- ( 5 12 + 12 ) ] & = 1 2 [ ( 4 12 )- ( 6 12 ) ] & = 1 2 [ ( 3 )- ( 2 ) ]= 1 2 [ 1 2 -0 ]= 1 4 & aligned
