Question

Can you guys help me? thank you

Write 4.9 x 10^9 m in standard notation.

Write 3.2 x 10^-5 in standard notation.

Answer 1

4.9 x 10^9 = 4,900,000,000

3.2 x 10^-5 = 0.000032

Explanation:

4.9 x 10^9 = 4,900,000,000: note the 9 places after the 4.

10^9 = 1,000,000,000; after substituting,

4.9 x 1,000,000,000 = 4,900,000,000

10^-5 = 0.00001

3.2 x 0.00001 = 0.000032
