Question

Write the following measurements and scientific notation:
1. 800,000,000 m
2. 0.0015 kg

Answer 1

8*10^8 and 1.5*10^-3

Answer 2

The key component to remember here is to keep the same significant figures

1) 800,000,000
==> 8 x 100,000,000
==> 8 x 10^8 m

2) 0.0015
==> 1.5 x 0.001
==> 1.5 x 10^-3 kg
