Need help rewriting this as a decimal.

Question

5*10^3 + 2*10^2 + 4*10^-1 =
If you can please show me how to do this that would be so helpful!

Answer 1

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.
