Evaluate: 12 + sqrt(- 5 + 7Ã—8Ã·4) =?	Choose the most appropriate option
A) 90 B) 91 C) 92 D) 93 E) 94
According to order of operations, inner brackets first where 7x8Ã·4 is first calculated since it has a multiplication and a division.   7x8Ã·4 = 56Ã·4 = 14   Hence   12 + sqrt(- 5 + 7Ã—8Ã·4) = 12 + sqrt(- 5 + 14)   = 12 + sqrt(9) = 12 + 81=
