1) Use Strong Induction to show that for each n ≥ 1, 10^n may be written as the sum of two perfect squares. (A natural number k is a perfect square if k = j 2 for some natural number j. These are the numbers 1, 4, 9, 16, . . . .)

2)Show that if A ⊂ B, A is finite, and B is infinite, then B \ A is infinite. Hint: Suppose B \ A is finite, and obtain a contradiction

Use the Well Ordering Principle (WOP) to show that 1+2+3+···+n= n(n+1)2 for all n ∈ N. Hint: In general, proofs using the WOP take the following format: proceed by contradiction and find a nonempty set of counterexamples, C, to the statement. The WOP is applied to C to find the smallest element. A contradiction is reached (somehow), which implies that C must actually be empty.
