Need help rewriting this as a decimal.
5*10^3 + 2*10^2 + 4*10^-1 =
If you can please show me how to do this that would be so helpful!
For each positive exponent, move decimal place one point to the right. For each negative exponent, move decimal place to the left.
5*10^3 = 5000
2*10^2 = 200
4*10^-1 = .4
Combine the three.
