    Answer:

    X=438Hz

    Explanation:

    From the question we are told that:

    Beat Frequency Fb=440Hz

    Actual Frequency F_a=3Hz

    Generally the equation for Frequency Heard X is mathematically given by

    X=beat\ frequency\ +\ actual\ frequency

    X=F_a+Fb

    X= 440Hz+3Hz

    X=438Hz
