Simplifying Logarithmic Expressions Without Using Tables
Simplifying Logarithmic Expressions Without Using Tables
The expression given is not clear due to the lack of parentheses and the use of ambiguous notation. Specifically, we need to know the bases of all the logarithms and the arguments for each term. However, for the sake of demonstration, let us assume the following expression:
3(log332/3) - 2(log39) (log33/8)
Step 1: Clarify the Expression
To ensure clarity, we should clearly define the expression using proper notation. The corrected expression would be:
3 log3(32/3) - 2 log3(9) log3(3/8)
Step 2: Apply Logarithmic Properties
Before simplifying, let's review some important logarithmic properties:
logb(MN) logbM logbN logb(M/N) logbM - logbN logb(Mn) n logbMStep 3: Simplify Each Term
Let's simplify each term one by one.
Term 1: 3 log3(32/3)
Using the property: logb(M/N) logbM - logbN
3 log3(32/3) 3(log332 - log33)
Simplify further:
3(log332 - 1) 3(log332 - log33) 3 log3(32/3)
Term 2: 2 log3(9)
Using the property: logb(Mn) n logbM
2 log3(9) 2 log3(32) 2(2 log33) 4 log33
Since log33 1, we have:
4 log33 4(1) 4
Term 3: log3(3/8)
Using the property: logb(M/N) logbM - logbN
log3(3/8) log33 - log38 1 - log38
Further simplification:
log38 log3(23) 3 log32
Thus, log3(3/8) 1 - 3 log32
Step 4: Combine All Terms
Now, we can combine all the simplified terms:
3 log3(32/3) - 2 log3(9) log3(3/8) 3(log332 - 1) - 4 (1 - 3 log32)
Simplify the expression:
3(log332 - 1) 3 log332 - 3
Thus, the final expression is:
(3 log332 - 3) - 4 1 - 3 log32
Simplify further:
3 log332 - 6 - 3 log32
Combine like terms:
3 log332 - 3 log32 - 6
Conclusion
In conclusion, the simplified expression is:
3 log332 - 3 log32 - 6
This can be further simplified if we know the value of log32, but for now, it is in its simplified form.
