#1011.9=1.0119xx10^3# in scientific notation.

Explanation:

A number written in scientific notation consists of a coefficient times the base 10 raised to a power (an exponent).

The coefficient consists of the significant figures (digits) in a number with the decimal moved so that it comes after the first non-zero digit, #1-9# inclusive. The exponent is the number of places the decimal is moved. It is positive if the decimal is moved to the left, and negative if the decimal is moved to the right.

#1011.9# has 5 significant figures.

#1011.9=1.0119xx10^3# in scientific notation.
