(b)
Answer to Problem 57PPE
Two pairs of positive integers a and b such that
are :
a = 90 , b = 2
a = 60 , b = 3
Explanation of Solution
Calculation:
Since
So, we need two positive integers a and b whose product is 180.
Let a = 90 , b = 2
Let a = 60 , b = 3
So, two pairs of positive integers a and b such that
are :
a = 90 , b = 2
a = 60 , b = 3
