## jylarai one year ago Two numbers are written in scientific notation. The number with a positive exponent is divided by the number with a negative exponent. Describe your result. Explain your answer

1. campbell_st

you need to know about the index law for division $\frac{x^a}{x^b} = x^{a-b}$ so in terms of scientific notation $\frac{10^a}{10^{-b}} = 10^{a - (-b)}$ what happens? do you think the power of 10 increases or decreases...?

2. jylarai

Increases

3. campbell_st

yes it does... and why does it increase... that is what you need to explain in your answer...
