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.

### Exponents

Welcome to the astonishingly clear introduction to exponents, roots, and logarithm. Learn in this

•  representation of exponents

•  roots and logarithms are two inverses of exponents

•  difference between common and natural logarithms

•  arithmetics with exponents and logarithms

•  Precedence -- PEMDAS or BODMAS (Exponent and Order)

•  introduction to squares and square roots

•  introduction to cubes and cube roots

All the above are given in a simple thought process.

Exponents and Logarithm Arithmetics

Exponents are repeated multiplication. Root is an inverse of exponent to find the base. Roots are also considered as a form of exponent with fraction power. Logarithm is another inverse of exponent to find the power. This page explains arithmetics with exponents and logarithms -- providing a list of formulas as known results or properties.

At the end, the roots and logarithms that are not defined are explained. For example: log_0 a and log_1 a are not defined. root(0)(a) is not defined.
