Answer:320

Step-by-step explanation:r = 4, so 2 x 4 = 8.

s = 6 and t = 3, so 6 x 3 = 18. 18 squared is 324.

u = 12, so 8 + 324 – 12, which equals 320.

Answer:

50

Step-by-step explanation:

2r + st^2 – u

2(4) + (6)(3)^2 – (12)

(8) + (6)(9) – (12)

(8) + (54) – (12)

62 – 12

50

Final answer: 50
