How do you write 345,000 in expended

I think you meant to say "scientific notation" ,

It would be 3.45 x 10^5

This is by moving the decimal to the right of the last number on the left and counting how many times it takes to move it there. The number you have counted gets put as the exponent on the 10.

If you meant scientific notation, the correct answer would be 3.45 x 10^5

Hope this helps
