The expression in standard form is [tex]1.6 \times10^{-6}[/tex]
Given the product of scientific notations:
[tex](8 \times 10^{-3}) \times (2 \times 10^{-4})[/tex]
This can be expressed as:
[tex]=(8 \times 2 ) \times (10^{-3} \times 10^{-4})\\=16 \times 10^{-3-4}\\=16\times 10^{-7}\\=1.6\times 10^1\times 10^{-7}\\=1.6 \times10^{-6}[/tex]
Hence the expression in standard form is [tex]1.6 \times10^{-6}[/tex]
