The given expression is:

10power of -2 divided by 10 -4power


This can be written as:


+%28%2810%5E%28-2%29%29%2F%2810%5E%28-4%29%29%29


==> +%28%281%2F%2810%5E2%29%29%2F%281%2F%2810%5E4%29%29%29+


This can be written as:


+%28%2810%5E4%29%2F%2810%5E2%29%29+


This is nothing but

+%28%2810+%2A+10+%2A+10+%2A+10%29%2F+%2810+%2A+10%29%29+


Cancelling few of the common terms, we get:


+10+%2A+10+


Thsi implies we get:


+10%5E2


Thus the solution... Which is expressed as the power of 10.
