The diameter of Sun is (1.4 ×10^8)m and the diameter of Earth is (1.2742×10^4)m . Show that the diameter of sun is nearly 100 times the diameter of Earth.

Answer 1

while the sun is indeed about 109 times as wide as the earth, the numbers given above are wrong. If you check,

10^8/10^4 = 10^4 = 10,000, not 100

google diameter of sun, earth and you will see that this problem is bogus as written.
