<PRE><B>Question 45408</B>
Calculate: (1.0 x 10^2)^-2 
=(1.0 x 10^-4)
=1/1000 or 1.0x10^-4

In a previous problem: (3*10^-4)^3 the answer turned out to be 2.7 * 10^-11. I have no idea how they got that. 

(3*10^-4)^3
=3^9 x 10^-12
=27 x 10^-12
Now, divide the 27 by 10 and multiply the 10^-12 by 10 to get:
2.7 x 10^-11
