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

    How about you giving this one a try ?

    Just follow the steps they told you to take,
    let me know what you get, and how you got it.

    square root(a+36+16+9)=15

    I don't know how to translate word to math

    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

    ok, I understand now , thank you
