Answer:

60 (C).

Step-by-step explanation:

FIrst off, the part that's most likely confusing you is the exponents and parenthesis. The exponents, if outside the parenthesis, affect everything inside the parenthesis. If the exponents are inside the parenthesis, however, they only affect the numebr they are attached to.

5+4 = 9, so 9^2 - (5 + 4^2).

4^2 = 16.

9^2 = 81.

81 - (5 + 16) = 81 - 21.

81 - 21 = 60.
