Question

Write the result in scientific notation.

(1.4 * 10^1)(8 * 10^4)

Answer 1

so this can be split into (1.4 * 8)(10^1*10^4) so you get..... (11.2)(10^5)

Answer 2

thanks

Answer 3

so then its not fully finished because you can simplify it further so youd end up with 1.12 * 10^6

Answer 4

I get it u round the number, thanks

Answer 5

\[(1.4 \times 10^1)(8 \times 10^4) \implies 11.2 \times 10^{4+1} \implies 11.2 \times 10 ^ 5\]

Answer 6

Answer 7

No I don't

Answer 8

no i dont what?

Answer 9

No I don't mean 1.12...

Answer 10

You didn't specify significant digits, so that's your final answer, but if it's a physics problem then it would be 1.12 x 10^6.

Answer 11

But either works, but yes as techno mentioned it would be more appropriate as 1.12x10^6.
