Today's class was all about logs.
The idea of logarithms was carried over to today's lesson, however, it answers the question "what happens if the base is not 10?" Since I know that all of you are just dying to know the answer to that, i shall now proceed and explain everything step by step.
These are examples of powers which have been converted from the exponential, to the logarithmic form.
In order to change a logarithm from the exponent to log form first the equation must be rewritten in the b^n=m form.
- 7^X=49 Definition of logarithm
- 7^X=7^2 Rewrite 40 as a power of 7
- X= ? Equate the exponents
log10 of 100=2
log7 of 7^4/3= 4/3
