Question

When 70,000 is written as 7.0 10^{n} what is the value of n ?

Can you please explain with some details?

Answer 1

`70 000=7\cdot10^4\\ \\840000000=8,4\cdot10^8\\ \\0,004=4\cdot10^(-3)\\ \\0,000000123=1,23\cdot10^(-7)`

Answer 2

I believe it's n=-4? It's a negative because the decimal moves to the right 4 times to get 70,000
