Math Problem Statement
Evaluate the expression. (Simplify your answer completely.) (a) log3(3)
(b) log9(1)
(c) log6(65)
Solution
Let's evaluate each logarithmic expression step by step.
(a) :
- The logarithmic expression asks the question: "To what power must the base be raised to get ?"
- In this case, means: "To what power must 3 be raised to get 3?"
- The answer is , since .
So, .
(b) :
- Any logarithm of 1 is 0, regardless of the base. This is because any non-zero number raised to the power of 0 is 1.
- Therefore, , since .
So, .
(c) :
- does not simplify to an exact integer since 65 is not a power of 6.
- To express it in a different way or estimate it, we can use the change of base formula:
- Using this formula: This would give a decimal approximation, but it's the exact way to express it algebraically.
Summary:
Would you like me to calculate the decimal approximation for part (c) or give more details on logarithmic properties?
