Can you help me with the plugging in question 8 on pg. 29?

Yep, can do!

The plugging in here is just picking numbers for x and y that work in the first equation. What multiples of 2 and 3 add to 11? Well, the first one that comes to mind for me is 2(1) + 3(3) = 2 + 9 = 11. So let’s say x=1 and y=3.

You can use your calculator here so now just evaluate 4^{1}8^{3}=2048 and see which answer choice lines up. Turns out 2^{11}=2048, so that’s the answer.
