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:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
