$2.46\times10^{-3}$

We start with the given expression: $0.3(8.2\times10^{-3})$ We rewrite the expression using the associative property: $0.3\times8.2\times10^{-3}$ We multiply the first two terms: $2.46\times10^{-3}$ Since 2.46 is between 1 and 10 and -3 is an integer, the number is in scientific notation.
