Use perfect induction to prove Theorem 7:( x + y ) ( x ′ + z ) = x z + x ′ y .
Prove the following theorem using induction THEOREM 39. If a 70 and m, n e Z, then aman = am+n and (a")" = amn. Moreover, if a, n EN, then a" EN.
Use mathematical induction to prove that for all n ∈ Z+ 5 + 22 + 39 + · · · + (17n - 12) = n ·(17n - 7)/2 4)(20) The relation R: Z x Z is defined as for a, b ∈ Z, (a, b) ∈ R if a + b is even. Prove all the properties: reflexive, symmetric, anti-symmetric, transitive that relation R has. If R does not have any of these properties, explain why. Is R an...

Prove by perfect induction the deMorgan formula for this, A-B=(A + B)
5. Use induction to prove the following for x,y EQ and n, mEN. (c) xn = 0 iff x = 0 (d) If x 〉 y 〉 0, then xn 〉 yn 〉 0
perfect sixth power. 9. Use the Fundamental Theorem of Arithmetic to prove that the product of any two odd integers is an odd integer.
1. To prove the theorem in detail. Theorem: det A for any n X n-matrix A can be computed by a cofactor expansion across the ith row of A, that is, det A H-1)adtAj Hint: Use induction on i, For the induction step from i to i+1, flip rows i and i+1 (How does this change the determinant?) and use the induction assumption. 1. To prove the theorem in detail. Theorem: det A for any n X n-matrix A can...
