Answer:
485 × [tex]10^{-10}[/tex]
Step-by-step explanation:
first we need to convert the number to fraction
0.0000000485
[tex]\frac{0.0000000485}{10000000000}[/tex]
it will be
[tex]\frac{485}{10000000000}[/tex]
or can be written as
[tex]\frac{485}{10^{10} }[/tex]
now we need to convert it to scientific notation
485 × [tex]10^{-10}[/tex]
