Correct. [[snippet]] >$$(3 \times 10^{-1}) \times (3 \times 10^{-1}) = (3 \times 10^{-1})^2$$ Split the power to individual bases, creating a power in scientific form. >$$(3 \times 10^{-1})^2=3^2 \times 10^{-2}$$ >$$3^2 \times 10^{-2}=9 \times 10^{-2}$$ Since the 10 part has an exponent of -2, shift the decimal point two places to the **left**. >$$9 \times 10^{-2}=0.09$$
