Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

### Finding Cube Root : Factorization Method

In this page, finding cube root using prime factorization, is introduced in a simple thought process.

What is the root(3)(216)?

• 6
• 6
• 18

The answer is "6".

Cube root is a form of root. In roots, we learned to perform prime factorization to find the root.
root(3)(216)
=root(3)(2xx2xx2xx3xx3xx3)
=2xx3
=6

Finding Cube Roots : To find cube root of a number, express the number in prime factors and group the factors.

eg: root(3)(1000) =root(3)(2xx2xx2xx5xx5xx5) =2xx5 =10

Note: This method is suitable for finding cube roots resulting in integers.
