A and b are positive integers and a-b=2 ... Evaluate the following: a) 2^a/2^b
b) 5^a/5^b
c) 4^0.5a/2^b

A) = 4.

B) = 25.

C) = 4.

Step-by-step explanation:

We are given that a and b are positive integers and that:

And we want to evaluate the following expressions.

Expression A)

We have:

This is equivalent to:

Therefore:

Substitute and evaluate:

Expression B)

We have:

This is equivalent to:

Again, substitute and evaluate:

Expression C)

Lastly, we have:

Note that 4 = 2². Hence:

Simplify:

Using the previous result:

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
