#### Explanation:

A general form number written in exponential form

#a * 10^b#

must have its *mantissa*, which is the name given to coefficient

#1 <= |a| < 10#

Your starting number has its mantissa written as

So, you have

#0.07 * 10^6 = 0.7 * 10^5 = 7 * 10^4#

You now have

Since the original number had one signifcant figure, its scientific notation version must have one significant figure as well.
