Question

what is the simplified form of (3.25x10^3)(7.8x10^6) written in scientific notation?

Answer 1

these are the answers
a) 2.535x10^10
b)2.535x10^18
c)2.535x10^19
d)2.535x10^9

Answer 2

first multiply your front terms:
3.25*7.8 = 25.35
however, in scientific notation, you want your largest term to be in the one's place to simplify your number.
This can be rewritten as 25.35 = 2.535*10 or 2.535x10^1
Now all you can to do is add the exponents of all the 10 terms
You have 10^3, 10^6, and now 10^1
3+6+1 = 10

That means your final answer is 2.525*10^10
