Question

Дано Df =24cm ,Fe=3de найти:de fe

Answer 1

DF = DE + FE = 24;

Т.к Fe=3de, то

DF = DE + 3DE;

DF = 4 DE;

DE = 24/4 = 6;

Fe=3de = 3*6=18;

Answer 2

To find the values of "de" and "fe," we need to understand what they represent.

"Df" usually stands for the focal length of a lens or mirror, and "Fe" could potentially represent the image distance in a lens or mirror equation. However, the provided information seems to be incomplete as it does not explicitly state what "de" and "fe" represent. To proceed with finding their values, we would need more context or information about the equations or situations in which "de" and "fe" are used.

If you could provide additional context or clarify what "de" and "fe" represent, I would be happy to help you find their values.
