If # (a,b,c,d) means you take the positive value of the square root of each term, then add the resulting values, and # (a,36,16,9)=15, then a = ?
please explain

No, you did not follow the instructions,
it says ...
take the square root of each number , THEN add them up, so
√a + √36 + √ 16 + √9 = 15
√a + 6 + 4 + 3 = 15
√a = 2
a = 4
