#70000 = 7 xx 10^4#

Explanation:

Count the number of times that you need to divide the number by #10# until you get a number that is less than #10#. That count gives you the exponent - the power of #10#.

Dividing by #10# is basically shifting the number one digit position to the right, so count the number of times you need to do that, to get a mantissa less than #10#.
