8. Which of the following is equal to 3 * 9?
Answer: B
9 * 3 is equal to 3 * 9.
9 multiplied by 3 yields the same result as 3 multiplied by 9, both equating to 27.
A) 6 * 6
6 multiplied by 6 equals 36, which does not match the product of 3 * 9. Thus, this option is incorrect.
B) 9 * 3
This option is correct because 9 multiplied by 3 is indeed equal to 27, which is the same as 3 multiplied by 9.
C) 3 * 3 * 6
This expression calculates to 54, as 3 * 3 equals 9 and then 9 * 6 equals 54. Therefore, this option is incorrect.
D) 3 * 3 * 3 * 3
This option represents 3 raised to the fourth power, equating to 81. Since its value does not match 27, it is incorrect.
Conclusion
The answer B) 9 * 3 is definitively correct as it directly matches the product of 3 * 9, both equating to 27. The other options fail because their products do not equal 27, demonstrating the importance of understanding multiplication commutativity in this context.
