Question

For each statement, identify and write out the hypothesis and the conclusion. you may have to introduce your own variable(s) to do it:

a) 2^n > n for all natural numbers n.

b) The reciprocal of every rational number is rational.

c) The sum of two odd integers is even.

d) Any natural number whose digits add up to something divisible by three is itself divisible by three.

e) Suppose f is a continuous function and A is a compact set. Then f(A) is also compact.

f) Any two real numbers have a rational number between them.

Explanation / Answer

a) n N, (2^n>n)

b) q Q, (1/q Q)

c) a,b 2Z+1, (a+b 2Z)

or

a,b odd , (a+b even )

or

a, b Z, 2|a-1, 2|b-1, (2|a+b)

d) n N, n=a1a2....am, 3|(a1+a2+...+am), (3|n)

e) f continuous, A compact set, (f(A) compact)

g) a,b Q, (c Q, acb)

Notation:

=any=for any

=exists=there exists

=belongs to=is in

You may also have something like e) f continuous, A compact set --> (f(A) compact)
