Question

Express 9 m in terms of cm, μm, and nm. Use proper scientific notation in your answers.

Answer 1

Answer:

$9\times10^2cm$

$9\times10^6 \mu m$

$9\times10^9nm$

Step-by-step explanation:

1 m = 100 cm

9 m = 100cm * 9 = 900 cm or $9\times10^2cm$

$1 m = 10^6 \mu m$

$9 m = 9\times10^6 \mu m$

$1 m = 10^9 nm$

$9 m = 9\times10^9 nm$
