Answer:

8) 27.75

10) See down below. May be 1.83 OR 123.75, depending on what your problem says

Explanation:

Problem 8)

Let's first take apart
2^(3), which will be 8. Now, let's plug that back into the equation real quick:

12 + (8 ÷
(2)/(3)) + 3.75

Since dividing a fraction can also be equal to multiplying the reciprocal of that same fraction, ÷
(2)/(3) can be re-written as: *
(3)/(2)

Let's put that into the equation now and solve:

12 + (8 *
(3)/(2)) + 3.75

= 12 + 12 + 3.75

= 27.75

Problem 10) (I'm unsure if the sign after 80 is ÷ or +, but I'll do equations for both)

(If the sign after 80 is ÷, check these steps on how to solve):

Same methods as problem 8. Let's first break down
4^(2), which will be 16. Then, let's set the ÷
(2)/(5) to *
(5)/(2) and solve:

80 ÷ (16 *
(5)/(2)) + 3.75

= 80 ÷ (40) + 3.75

=
(80)/(40+3.75)

= 1.82857

(If the sign after 80 is +, check these steps):

80 + (16 *
(5)/(2)) + 3.75

= 123.75
