Your seeking help on any topic in mathematics leaves a lot of options open. You haven't specified at what level of school/university you are.

However, I shall give some links on some interesting topics in mathematics, you may choose from these.

De Moivre's Theorem :- Use the hyperlinks given.

]]>((A+B)B')+AB

((A v B) ^ ~B) v (A ^ B)

The easiest way to do this is to make a truth table:

A | B

------

0 | 0

0 | 1

1 | 0

1 | 1

Then plug each of the values in. For the first ordered pair (0,0), it would be:

((0+0)0') + 0*0 which is (0*1) + (0) which is 0.

Try the others, post your results here and we can check them for you.

]]>((A+B)B')+AB

Does anyone understand this

or this

Find all ordered pairs (A, B) that satisfy the following expression: (A + B)' ((AB)')]]>
