All of these questions will be exponents and variables.
Answer:
54
Step-by-step explanation:
to evaluate substitute b = 18 into 3b
3b = 3 × 18 = 54
assuming 
Then the column values for base five here are
5³ 5²

We can get 1 × 5³ = 125 → 219 - 125 = 94
We can get 3 × 5² = 75 → 94 - 75 = 19
We can get 3 x
→ 19 - 15 = 4
and 4 = 4 × 
Thus
= 
As a check
(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219
