149

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

Step-by-step explanation:

Substitution:

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

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

(10) / (5) + 147

50 + 147
