Question

(2x10^6) x (0.00009)

Answer 1

180

First, let's state what we are given:

`(2\text{ }*10^6)*(0.00009)`

Then we convert the decimal to standard form and solve:

`\begin{gathered} 0.00009\text{ = 9}*10^(-5)\text{ in standard form} \\ 2\text{ }*10^{6\text{ }}*9*10^(-5) \\ =\text{ 2}*9\text{ }*10^(6-5) \\ =\text{ 18 }*10^1\text{ = 18}*10 \\ =\text{ 180} \end{gathered}`

(2x10^6) x (0.00009)​ = 180
