Herbert's book "Random Kindness and Senseless Acts of Beauty" was published in February 1993 speaking about true stories of acts of kindness. The phrase is commonly expressed as the suggestion to "Practice
Powerful number "k". Such an integer is called a "k"-powerful number, "k"-ful number, or "k"-full number. are "k"-powerful numbers in an arithmetic progression. Moreover, if "a", "a", ..., "a" are "k"-powerful in an arithmetic progression with common difference "d", then "a"("a" + "d"), ..., "a"("a" + "d"), ("a" + d) are "s" + 1 "k"-powerful numbers in an arithmetic progression. We have an identity involving "k"-powerful numbers: This gives infinitely many "l"+1-tuples of "k"-powerful numbers whose sum is also "k"-powerful. Nitaj shows there are infinitely many solutions of "x"+"y"="z" in relatively prime 3-powerful numbers(Nitaj, 1995). Cohn constructs an infinite family of solutions
