anonymous · Answer

9.52 x 10^11

anonymous · Answer

the poweres get added

anonymous · Answer

okay, thanks! Can you help me with this one? (5.8 x 10^-6)^4

anonymous · Answer

I know that you have to add the powers but scientific notation still is confusing for me...

anonymous · Answer

yeah it is very confusing just need to practise.

anonymous · Answer

for the 2nd one i get 0.058 which is 5.8x10^-2

anonymous · Answer

once again you just add the powers 10^-6 + 10^4 = 10^-2

anonymous · Answer

if you can find and use the 10^x button on the calculator then practice that.

multiplying is associative meaning that the order in which you multiply is not important:

   3.4 x 10^3
* 2.8 x 10^8
--------------
 272  x 10^(3+8)
 68
----------------
 9.52 x 10^(11)

since the left part is already in good decimal form there is no need to adjust it :)
