The sum of two positive numbers is 88 and their product is 1927. The positive difference between them is:
6
For two numbers with sum S and product P, the positive difference is \(\sqrt{S^2-4P}\).
\(\sqrt{88^2-4\times1927} = \sqrt{7744-7708} = \sqrt{36} = 6\).
Hence, the positive difference between the two numbers is 6.
