Question

examine the proposition indicate if it is True or False: then prove if you are correct

A)

for every a that belongs to integer set and b that belongs to natural numbers there exists an unique (q, r) such taht (q, r belongs to integer set, a = bq+r, and r<b)


T  F


B)

(a, b, c, d. e belong to interger set such that (ab= c and ad = e)) then a =< (c, e)


T  F


C)

(p belong to prime numbers and p > 60) then p + 9 belong to {composites}


T  F


D)

3 is a divisor of a then a belongs to {almost primes}


Explanation / Answer


A)True

B)False

C)True (As the primes > 60 are always odd, sum of two odd numbers (p and 9) is always an even number,so composite)

D) False (As the even multiples of 3 are all even (not primes))
