2^2 , or 4
since the exponents have the same base, we can subtract the exponent of the numerator by the exponent in the denominator.
So 2^-3 - 2^-5 = 2^(-3-(-5)) = 2^2
The new exponent is 2 because -3-(-5) is equal to 2.

You would have to calculate the percent first.
Add the total number of students
3420+4680= 8100 students TOTAL
Then you would divide the amount of students by the total
3420 part time/8100 students total = .42 or 42%
4680 full time/8100 total = .58 or 58%
Then you multiply the percentages by 90
(90)(.58)= 52.2
(90)(.42)= 37.8
Rounded
52 full time and 38 part time students
Answer:
The answer is Ccccccccccccccccccccc

We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with
,
,
, and
respectively since each one is 1 point more than the last.
Add all of these values up and set it all equal to
.

Now, simplify.

Subtract
on both sides.

Divide both sides by
.

Since Louise's score is
, the answer is
.
<h3>Double-checking</h3>
To verify our answer, add the point totals
,
,
, and
.
This equals
, so we can be sure the answer is correct.
