Answer:
Step-by-step explanation:
The LCD here is 10.
Multiplying numerator and denominator of (4*10^2) by 10 results in:
40*10^3
-------------
10
and rewriting (2x10^-1) with positive exponent in the denominator results in:
2
---------
10
So, before simplification, this difference comes out to be:
40000 - 2 39998 19999
----------------- = ---------------- or ------------
10 10 5
