1st
1. Ignore the polynomials at the start.

2. I wonder how the space shuttle can have a speed of 6 x 10^8 m/s when no object can travel faster than the speed of light as 3 x 10^8 m/s.

3. For 19(i), because there is a square root, I try and round the number off to the nearest perfect square or a number which square roots to a nice number (like square root of 6.25 is 2.5).
