Answer :
180
First, let's state what we are given:
[tex](2\text{ }\times10^6)\times(0.00009)[/tex]Then we convert the decimal to standard form and solve:
[tex]\begin{gathered} 0.00009\text{ = 9}\times10^{-5}\text{ in standard form} \\ 2\text{ }\times10^{6\text{ }}\times9\times10^{-5} \\ =\text{ 2}\times9\text{ }\times10^{6-5} \\ =\text{ 18 }\times10^1\text{ = 18}\times10 \\ =\text{ 180} \end{gathered}[/tex](2x10^6) x (0.00009) = 180
