Correct Answer: 64
Work Step by Step
The associative property only works when all the numbers involved are either being multiplied or added together. For example, $(2+3)+4=2+(3+4)$ works, and $(2\times3)\times4=2\times(3\times4)$ works. However, $(2+3)\times4\ne2+(3\times4)$ because the associative property doesn't work when using a combination of addition and multiplication.
