#3.4xx10^5#

Explanation:

Scientific notation standard form requires the decimal to be to the right of the left-most non-zero number: For example: #2.5 xx 10^4# is in standard form, but #25 xx 10^3# is not.

For your example:
#0.5(6.8xx10^5) = 0.5 xx 6.8 xx 10^5#

Multiply like terms: #0.5*6.8 = 3.4#

#0.5(6.8xx10^5) =3.4xx10^5#
