Answer:
12
Step-by-step explanation:
64+52=118 studied in the cafeteria or lounge
but 20 studied in both, so 118-20 = 98 studied there in total
110 -98 = 12

To raise 4x/y to a power, raise the numerator and denominator to the power, and then divide.

Expand (4x)².

Calculates 4 to the power of 2 and gets 16.
