turn standard form into scientific notation:

Question

1. 12457.686 m
2. 0.000065423 g
3. 128.90 g
4. 0.0000007532 m

turn scientific notation back to standard form:
1. 1.37 x 10^4m
2. 2.875 x 10^2g
3. 8.755 x 10^-5g
4. 7.005 x 10^-3m

Answer 1

All it takes is movement of the decimal place. I will do one of each problem.

1. 12457.686 m = 1.2457686 * 10^4
(Move decimal places to the left.)

1. 1.37 x 10^4m = 13,700
(Move decimal place to the right.)
