0.8 is a decimal number to change it to a fraction make the denominator equal 10 because we have one decimal place
[tex]0.8=\frac{8}{10}[/tex]we can simplify it by divide up and down by 2
[tex]0.8=\frac{8}{10}=\frac{4}{5}[/tex]To write it with a negative exponent we will reciprocal it and make the exponent -1
[tex]0.8=(\frac{10}{8})^{-1}=(\frac{5}{4})^{-1}[/tex]To write it as a product of a single-digit integer and an integer power of ten
Make the denominator 10 = 10^(-1)
[tex]0.8=8\times10^{-1}[/tex]Let us do the same with 0.0000006
[tex]0.0000006=\frac{6}{10000000}[/tex]Because we have 7 decimal places the denominator has 7 zeros
We can divide up and down by 2 to simplify it
[tex]0.0000006=\frac{6}{10000000}=\frac{3}{5000000}[/tex]Let us write it with a negative exponent
[tex]0.0000006=(\frac{10000000}{6})^{-1}=(\frac{5000000}{3})^{-1}[/tex]The number as a product of single-digit times 10 to the power is
[tex]0.0000006=6\times10^{-7}[/tex]You can do the last number in the same way
