Answer:

#2.0xx10^(12)#

Explanation:

Write as #2000000000000.0#
#color(white)("dddddddddddddddd.d")uarr#
#color(white)("dddddddddd")"my added decimal point"#

The objective in this case is to have:

#color(white)("dddddd") 2."something decimals"xx10^("some number")#
#color(white)("dddddd")uarr#
New decimal point position

If we count all the 0's between the 2 and to the decimal point I inserted, you have a count of #color(red)("twelve 0's")#

#color(white)("d")ubrace(2."something decimals")xx10^(color(red)("some number"))#
# color(white)("ddddddd.d") 2.0color(white)("ddddddd.")xx10^(color(red)(12))#
