#3xx10^3#

Treat this in exactly the same way as # (12x^8)/(3x^5)#

Divide the numbers and subtract the indices to give: #4x^3#

#(9xx10^5)/(3xx10^2)#

Divide the numbers and subtract the indices:

=# (cancel9^3xx10^(5-2))/(cancel3)#

#3 xx10^3#

The answer is in scientific notation and no adjustment is necessary.
