Remember operation order rules...

[7(5-3)^2 + 14] = 42

(5-3) first, ^2 second, *7 third, + 14 fourth

(8+3*18) = 62

3*18 first, + 8 second

2^2 (2^4 - 9) = 28

2^4 first, - 9 second, * 2^2 third

42 * 62 = 2604
2604 / 28 = 93

Answer is C) 93

[7(5-3)^2]=[7*2^2]=28
[8+3*18]=8+54=62
[2^4-9]=16-9=7

([28+14]*62)/(4*7) = 93

The denominator is 28: (4*(16-9))

The is [7(2)^2+14](8+3*18) which is 2604
the answer is 93
