Algebra Puzzle – Critical Thinking 15
Critical thinking challenges like this one can be as much a part of a math class as learning concepts, computations, and formulas.
Challenge:
What is the smallest positive integer p such that 1080p is a perfect cube number?
The Absolute Best Book to Challenge Your Smart Student!
The correct answer is 25.
First, find the factor of 1080p. The prime factors of 1080p are:
\(2^3×3^3×5×p\)
In order for \(2^3×3^3×5×p\) to be a perfect cube, each prime factor must come in sets of triples. Since, we have \(2^3×3^3×5\), thus, we only need to change 5 to \(5^3\). Therefore, p equals to \(5^2\) or 25.
