ok the question is Describe how you would help a friend who needs to simplify the expression 4x to the fourth power over 2x to the fifth power plz help thanks

Act like one of the teachers in here, explain with words and step by step examples. As in: " first, you take the numbers and functions from the sentance and convert them into math symbols"...

It isn't clear from your description if the 4 is raised to the fourth power and the 2 is raised to the fifth power or just the X raised to those powers. I will assume just the X is raised to those powers as I show below. If it is something different, I think you will understand what to do.

(4X

^{4})/(2X

^{5}.

Divide 4 by 2 to obtain 2. Move the X in the numerator to the denominator.

(2)/(X

^{5}X

^{-4}.

Now combine the X terms.

2/(X

^{5-4})=2/X

^{1}=

2/X.
