Chapter 7 - Exponents and Exponential Functions - 7-2 Scientific Notation - Lesson Check: 1

Answer

$7\times10^{-4}$

Work Step by Step

To get the number $0.0007$ into scientific notation, we must move the decimal place 4 places to the right. We use this $4$ as the exponent of $10$, but since the original number is less than 1, we must use a negative exponent of $10$. We end up with $7\times10^{-4}$
