    Step-by-step explanation:

    Evaluate u/z + x y^2 where u = 10, x = 3, y = 7 and z = 5:

    u/z + x y^2 = 10/5 + 3*7^2

    The gcd of 10 and 5 is 5, so 10/5 = (5*2) / (5*1) = 5/5*2 = 2:

    2 + 3*7^2

    7^2 = 49:

    3*49 + 2

    3*49 = 147:

    147 + 2

    2 + 147 = 149:

    Answer: 149

    Substitution:

    (10) / (5) + (3) * (7) ^ 2

    (10) / (5) + (3) * 49

    (10) / (5) + 147

    50 + 147
