Question 1153140: The exposure index EI for a 35 millimeter camera is a measurement of the amount of light that hits the film. It is determined by the equation
EI = log2
f 2
t
,
where f is the "f-stop" setting on the camera, and t is the exposure time in seconds. Suppose the f-stop setting is 4 and the desired exposure time is 2 seconds. What will the resulting exposure index be?
EI =

Regarding the equation, I have only one question :

        What is written here, in this mysterious format ?


And why I should look in it, in all ?


Isn't it better to re-direct it to the  TRASH  SECTION ?   (and  NEVER  see it again . . . ? )
