    look at this set of info:


    f(5,7,4)=118
    f(3,9,6)=300
    f(2,5,4)=91
    f(3,4,?)=244

    f is some function.

    now find f(,,)
    and the missing number.

    f means (first term +second term's square + third term's cube ) = result

    (5+49+64) = 118

    (3+81+216) = 300

    (2+25+64) = 91

    missing number is cube root of (225) =6.08

    (3+16+225) = 244

    f(3,4,?)=244




    .
    according to me the missing number may not be in decimals..so please check the question..

    either the 244 must be 144 or the second number 4 may be 10 then you can get an answer in proper way...

    sorry 😔
    the last result was meant to be 144 and there seems to be a slip of fingers ....
    and yeah your function is right...😀
