Question

Multiplication (Use significant figure rule)

(5.430*10^4)(1.44*10^8)

So far I know it would be down to: 7.8192*10^12

But after that I am confused.

Answer 1

rebecca this is right so in this way with this result

Answer 2

Yes, but it does not follow Sig Fig. My answer has to have at least 3 significant figures, but I am confused on how to find them.

Answer 3

do you know the scientific notation of a big number like 1,32*10^23 for example

Answer 4

I am aware of scientific notation, and how it works. I am confused on scientific notation with significant figures. However, I think my answer would have to be 7.82*10^12 because I need 3 significant numbers, I would round up the 7.8192 to 7.82 because that would be 3 significant numbers?
