Final answer:
To expand the logarithm log₃9, we recognize that 9 is 3 squared and use the property of logarithms to simplify log₃(3^2) to 2 * log₃(3). Since log₃(3) equals 1, the final answer is 2.
Step-by-step explanation:
The question asks to expand the logarithm log₃9. To expand this logarithm, we can use the property of logarithms that states the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number. Since 9 is 3 squared (3^2), we can write this as:
log₃(3^2)
Using the aforementioned property, we can simplify this logarithm to:
2 × log₃(3)
Now, as the base of the logarithm and the number inside the logarithm are the same (both 3), we can simplify this further since log₃(3) equals 1:
2 × 1 = 2
Thus, the expanded form of log₃(9) is simply 2.
