The other variables all build upon u, so use the Picking Numbers strategy: pick a small number for u and find the values for r, s, and t. For instance, if u = 1, then t = 2u, so t = 2; s = 5t, so s = 10; and r = 3s, so r = 30.
So, \(\frac{rst}{u^3} = \frac{30*10*2}{1*1*1} = 600\)
The correct answer is (E).
So, \(\frac{rst}{u^3} = \frac{30*10*2}{1*1*1} = 600\)
The correct answer is (E).
