Answer:

#7.0xx10^5#

Explanation:

We want our number in the form:

#"decimal"xx10^"movement of the point"#

Write your number and localize the decimal point:

#700,000color(red)(.)#

now move the point to the left up to reaching the first non-zero number:

#7.00000#

Count the movements of your point (5 movements to the left) and use this value as positive exponent of #10#:

#7.0xx10^5#
