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
