we are given the following numbers:
[tex]0.0000029,0.000000024,0.00002,0.00000027[/tex]
We can rewrite each of these numbers in decimal notation by moving the decimal point to the right and multiplying by 10 to an exponent equal to the negative of the times we moved the decimal point, like this:
[tex]\begin{gathered} 0.0000029=2.9\times10^{-6} \\ 0.000000024=2.4\times10^{-8} \\ 0.00002=2\times10^{-5} \\ 0.00000027=2.7\times10^{-7} \end{gathered}[/tex]
Now, the smaller the number of the exponent of ten the least the number is, therefore, the order from least to greatest is the following:
[tex]2.4\times10^{-8}<2.7\times10^{-7}<2.9\times10^{-6^{}}<2\times10^{-5}[/tex]
