    60x^3

    Step-by-step explanation:

    Given:

    4/15x^3 and 5/12x^2

    finding LCM of denominators (15x^3,12x^2)

    for variable x, as x^3 is the heighest power so we'll keep x^3

    now for the numeric part

    15 = 3*5

    12=3*4

    common factor is 3, so

    3*4*5 = 60

    hence LCD = 60x^3!
