a. Let's set a=3, b=1
In other words 
is odd, i.e. has remainder 1 when divided by 2. 
b. Let
There are 2n terms in the last factor. All the terms of the form
are odd. So when we add up an even number of them, we get an even number, call it 2m.
We've shown 
is divisible by four. 
Merry Christmas!
Decantation and filtration are both methods of separating mixtures. Decantation is the process of separating the liquid phase of a mixture from the solid precipitate, by pouring very carefully the liquid away. Filtration is the process of passing the entire liquid through a filter, where the solid precipitate will be trapped in the filter. Someone would need to use filtration if he wanted to filtrate the entire quantity of the solution. Also if the solid phase of the solution was not a steady sediment and dispersed in the entire liquid phase.
