I happened to come across an interesting mistake made by a maths student. The mistake inter-mixed the principles of algebra with logarithm. The maths question is to solve the value of x given the expression: 2+ log (5x - 1)  = log 3x The expression, after transferring the "log (5x -1)" to the right side ...

Saturday, September 22nd, 2007

Logarithm term is represented as logaN. The small "a" is called the "base". It is not necessary that all term of logarithm uses the same base. It can be  log2X,   log10X , etc. What if we want a certain base but is not given in the logarithmic problem? Let's explain with an example.        ...

Logarithm | common mistakes made

Saturday, September 22nd, 2007

First of all, let me explain the syntax of writing the Logarithmic term. Logarithmic term is expressed in the form of logaY, where the letter "a" is known as the "base". NOTE: If the base is 10, normally we will leave the logarithmic term as logY (without writing the base 10). The explanation ...
