evaluate : 13 + sqrt ( - 4 + 5 ã — 3 ã · 3 ) = ?
"according to order of operations , inner brackets first where 5 x 3 ã · 3 is first calculated since it has a multiplication and a division . 5 ã — 3 ã · 3 = 15 ã · 3 = 5 hence 13 + sqrt ( - 4 + 5 ã — 3 ã · 3 ) = 13 + sqrt ( - 4 + 5 ) = 13 + sqrt ( 1 ) = 13 + 1 = 14 correct answer c ) 14"
add(13, sqrt(subtract(divide(multiply(5, const_4.0), 3), 4)))
