Answer 1

Answer:

6

Step-by-step explanation:

      90

-------------------

10 + (3^2 - 4)

first we look at the parenthesis. take 3 to the second power, and it equals 9

     90

------------------

10 + (9 - 4)

next, still in the parenthesis you subtract 4 from 9

   90

--------------

10 + (5)

next add 10 plus 5

90

-------   =       6

 15

now divide 90 by 15 and you get your answer, 6
