Logarithmic Expressions Worksheets
What are Logarithmic Expressions?
In the intermediate level of mathematics, you have learned various tactics to resolve and simplify expressions with exponents. For instance, if you have an expression x3 × x5, then the powers will add to make x8. Similarly, there are other logarithmic expressions that help in resolving log-based questions easily and swiftly.
logb mn = logb m + logbn.
logb (m/n) =logb m - logbn
logbmn = n · logbm.
However, you must keep in mind that similar to the exponents, the above rules work if and only the bases are the same. For instance, logbmn = logbm + logdn can not be simplified because the bases are not the same.
Pie charts can be misrepresented...
Here are two ways that
this can happen:
1. Leaving out one or more of the parts of the whole - this increases the percentages of the other parts.
2. Not defining what the whole stands for -parts have no meaning.<
