Question #ce7da

Answer 1

The number is already in standard form.

Explanation:

Scientific notation (also called exponential notation) is to write a number in the form of
`a*10^x`

where
a: `1<=a<10`
x: the number of places that we have to move the decimal point.

Since in your case a (7.863) is already between 0 and 10, so It is given in standard form.
