2 Summations These three program snippets beep (by calling the beep() method). Looking at the code in each case you will see that the number of beeps depends only on the variable n. For each of the four a) write down a closed formula for the number of beeps using n (such as "3n+4" which is not one of the solutions) and b) write down how much that is for n = 1000. [3/each = 9]

When working with very large or very small numbers we don't always want to write out all of the zeros. One strategy for shortening these numbers is to write these them in terms of powers of ten. To do this, we consider how many times we need to multiple ten by itself to get the desired output. Example: • 10 = 10¹ • 100 = 10 x 10 = 10² • 1000 Try it = Answer: 10 × 10 × 10 = 10³ Write ten thousand as a power of ten. Calculator
