5) Distance from earth and moon
= 384,000 kilometers
= 3.84 x 10^5 kilometers <-------------scientific notation form
----------------
6)
1.969 x 10^8
= 196,900,000 <-------------standard form
7)
6 x 10^0 / 7 x 10^-3 = (6/7) x 10^(0 + 3) = 0.857 x 10^3 = 857
About 857 times longer as anaconda compared to an ant.
8)
10 cm a year but a year has 52 weeks = 0.19 cm ≈ 0.2 cm per week
So you should you mm to measure and it's more accurate. So it's about 2 mm per week.
