Jill is trying to prove the following number trick: Choose any number. Add 3. Double it. Add 4. Divide by 2. Take away the number you started with. Each time Jill tries the trick, she ends up with 5. Clearly demonstrate a proof by:
a) inductive reasoning:
b) deductive reasoning:
A. Expand each power using Properties I to V.
1.) (c+d)^5
2.) (x-y)^4
3.) (3-x)^4
4.) (u-v)^8
5.) (3b+y)^5
B. Find only the first three terms in the expansion.
1.) (a+20)^14
2.) (c+y)^k
C. Compute each factorial expression.
1.) 6!
2.) 8!
3.) 3!4!
