Hi, thanks, @oobleck that looks like you're not the real teacher.
Also could someone help with:

What is the order of theese numbers from LEAST to GREATEST?
2.7x10^8,2.3x10^11,6.5x10^12,4.8x10^21
No one? Ok.
2.7x10^8
2.3x10^11 = 2300x10^8
6.5x10^12 = 65000x10^8
4.8x10^21 = 48000000000000x10^8
still not sure?
