Step-by-step explanation:

The small number above the 2 is called an exponent, and we use exponents to shorten a number so it's not so large. So here, the 6 is an exponent, and when we have a problem like this where we have to figure out something like 2^6, as shown above, we grab the base number, which in this case is 2, and we multiply it by itself 6 times, since 6 is the exponent. So basically you have to multiply the base number (2) by itself the same number of times as whatever the exponent is. So we have 2 × 2 × 2 × 2 × 2 ×2, and when you multiply all of this, you get 64. So the module has 64 pages.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
