I'm pretty sure that it is 140. Hope I helped!
Yes.
For example, the LCM of 12 and 36 is 36, because factoring these numbers gives
12 = 2^2 * 3
36 = 2^2 * 3^2
So, to match them, just multiply the twelve by 3, then they're both 36.

Use a calculator it will help.
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
.
