Answer 1

hi,
four times ten to the negative fourth =\[4\times 10^{-4}\]

three times ten to the negative ninth =\[3\times10^{-9}\]

sooo...
four times ten to the negative fourth multiplied by the quantity three times ten to the negative ninth =
\[4\times10^{-4}\times3\times10^{-9}\]
=\[12\times10^{-13}\]
=\[1.2\times10\times10^{-13}\]
=\[1.2\times10^{-12}\]

the final answer is 1.2 * 10^(-12)
