(i) The height of Mount Everest is 8848 m. Write it in standard form.
(ii) The speed of light is 300000000 m/sec. Express it in standard form.
(iii) The distance from the earth to the sun is 149600000000 m. Write it in standard form.
(i) The height of the Mount Everest is 8848 m.
In standard form, we have:
$8848=8.848 \times 1000 \mathrm{~m}=8.848 \times 10^{3} \mathrm{~m}$
(ii) The speed of light is 300000000 m/s.
In standard form, we have
$300000000=3 \times 100000000 \mathrm{~m} / \mathrm{s}=3 \times 10^{8} \mathrm{~m} / \mathrm{s}$
(iii) The Sun - arth distance is 149600000000 m.
In standard form, we have:
$149600000000=1496 \times 100000000=1.496 \times 1000 \times 100000000=1.496 \times 10^{3} \times 10^{8}=1.496 \times 10^{11} \mathrm{~m}$
