true or false Every real number has a multiplicative inverse.

Find the products AB and BA to determine whether B is the multiplicative inverse of A. - 4 - 3 +BHR] B= 0 1 A = AB= - 3 No Yes -4 - 4 1 BA= Is B the multiplicative inverse of A?

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
