Answer

$8.4\times10^{-4}$

Work Step by Step

We are given the number $.00084$. Step 1: To write this number in scientific notation, we move the decimal point to the right until the original number is 8.4. Step 2: Since the original number was less than 1, we moved the decimal by 4 negative places. In other words, we will raise 10 to a power of -4. Now, we write the product of the two numbers found in Step 1 and Step 2. $8.4\times10^{-4}$
