# Let A be the set of all string of a’s and b’s of length 4. Define a relation R on A as follows: For every s , t ∈ A , s R t       ⇔     s   has the same first two characters as  t . Is abaa R abda? Is abaa R abda? Is aaaa R aaab? Is baaa R abaa?

To determine

(a)

Whetherabaa R abba is true for the relation R.

Explanation

Given information:

Let A be the set of all strings of a’s and b’s of length 4.A relation R on A is as follows: For all s, t ∈ A, s R t ⇔ s has the same first two characters as t.

Calculation:

A= set of al strings of a and b of length 4

To determine

(b)

Whetheraabb R bbaa is true for the relation R.

To determine

(c)

Whetheraaaa R aaab is true for the relation R.

To determine

(d)

Whetherbaaa R abaa is true for the relation R.
