How many pairs of (m,n) are there such that m^2 +n^2 =50
Answer:  pairs.

Several pairs of whole numbers (m,n) satisfy 19m + 90 + 8n = 1998 (100,1) is the pair with the smallest value for n. Find m such that (m,n) is t he pair with the smallest value for m

Several pairs of whole numbers (m;n) satisfy :

What is the largest integer n such that there is a multiple of 4 less than n² but greater than n²+\(\frac{2016}{n^2}\)?

Number 6 is written as sum of two positive integers in three different ways: $6=1+5=2+4=3+3.$ (order does NOT matter). That is, there are exactly three different pairs of positive integers that add to make six. How many pairs of positive integers that add to make 1000?
