Question

Use scientific notation to find 508,000,000,000 x 0.0000073. Write the answer in scientific and in standard form.

Answer 1

Answer:

3.7084 x 10^6   (scientific form)

3,708,400 (standard form)

Step-by-step explanation:

Expressing these numbers in scientific notation:

508,000,000,000 = 5.08 x 10^11

0.0000073 = 7.3 x 10^-6

Hence,

508,000,000,00 x 0.0000073

= (5.08 x 10^11)     x    (7.3 x 10^-6)

= 5.08 x 7.3 x 10^11 x 10^-6

= 37.084 x 10^ [11 + (-6)]

= 37.084 x 10^5

= 3.7084 x 10 x 10^5

= 3.7084 x 10^6   (scientific form)

= 3,708,400 (standard form)
