Answer 8

i just took the quick check here are my answers. 100%

1- 4.22 x 10^-3 (d)
2- 7.08x10^-8 (a)
3- 6.1x10^-7 (a)
4- 1.25 x 10^-4
5- doubling n results in a doubling of the value of the expression (c)
6- 2.45x10^5 (b)
lastly 7- 3x10^3 (a) (it may not seem that way, but most precision would be 3.212x10^3, so least would be 3x10^3. good luck!)
