Answer 3

To check if the expression $4^5 + 8^3 - 16^2$ is divisible by 80, we need to calculate its value and then see if it's divisible by 80.

Step 1: Calculate the expression. $4^5 + 8^3 - 16^2 = 1024 + 512 - 256 = 1280$.

Step 2: Check if it's divisible by 80. To see if a number is divisible by 80, we need to check if it's divisible by both 8 and 10 since $80 = 8 \times 10$.

Is $1280$ divisible by 8? Yes, because $1280$ ends in a zero, and any number ending in zero is divisible by 8.

Is $1280$ divisible by 10? Yes, because $1280$ also ends in a zero, and any number ending in zero is divisible by 10.

Since $1280$ is divisible by both 8 and 10, it is also divisible by their product, which is 80.

So, yes, $4^5 + 8^3 - 16^2$ is divisible by 80.
