You have these positions for the format of your number:
X,XXX,XXX,XXX.X

The ten millions place is shown here using P:
X,XPX,XXX,XXX.X
You want to round to that place marked as P.

The given number rounded to the nearest ten millions place is:
1,040,000,000.0
and the significance of the digits to the right-hand side of the "4" are now lost, but we are instructed to convert to Scientific Notation.

Scientific Notation here will be move decimal point nine places to the left, and apply as an adjusting factor:
.
We ordinarily write an "x" instead of the multiplication dot.
