Answer:


5 and 3


Step-by-step explanation:


p + q = ( p - q )³


Let p - q be k

So p + q = k + 2 q



So this means that we have :

k + 2 q = k³

= > k³ - k = 2 q

= > k ( k² - 1 ) = 2 q

= > k ( k + 1 )( k - 1 ) = 2 q


q is a prime with only 2 factors .

q will therefore have q and 1 has factors .


This means that we can group the data so that :

k - 1 = 1

= > k = 2


k + 1 = q

= > q = 2 + 1 = 3


Hence p - q = 2

= > p - 3 = 2

= > p = 2 + 3 = 5


There are only two possible primes : 5 and 3.
