Answer:
c=-5
d=1
Step-by-step explanation:

I'm going to reorder the left-hand side. Multiplication is commutative.

Since the bases are the same in
and the operation is multiplication, I'm going to add the exponents giving me:

So this implies we have two equations to solve:
and 
So the first equation can be solved by dividing both sides by 4 giving you
.
The second equation can be solved by subtracting 2 on both sides giving you
.
Answer:
150656
Step-by-step explanation:
i used a calculator and google
Ben drinks 3 1/2 liters of tea every 40 minutes.
This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).
Now, let's multiply each side by 3.
1.75 * 3 = 5.25 (aka 5 1/4)
20 * 3 = 60 minutes (an hour)
He drinks 5 1/4 liters of tea in one hour.
