Answer:
1.721 × [tex]10^{10}[/tex]
Step-by-step explanation:
A number expressed in scientific notation is of the form
a × [tex]10^{n}[/tex]
where 1 ≤ a < 10 and n is an integer
Given
17, 210, 000, 000 , then
= 1.721 × [tex]10^{n}[/tex]
The decimal point has to be moved 10 places to the right of where it has been repositioned.
A move to the right is + while a move to the left is -
1.721 × [tex]10^{10}[/tex] ← in scientific form
