309.3 times (10-10) = 0
(309.3 times 10) - 10 = 3083
percentage = 5 x 1010%5000 x 105 x 100% = 5000 x 107% or 5 x 1010%
2.5 x 1010 x 3.5 x 10-2 = 88.375
55,550.
2.5*1010*3.5*(10-7) = 26512.5
2.5 x 1010 x 3.5 x 10 - 7 = 88368

You calculate this as 1010 over 66 - that is:(1010 x 1009 x 1008 x 1007 x ...) / (1 x 2 x 3 x 4 x ...) with a total of 66 numbers at the top and at the bottom. Excel can help you with the actual calculations.
0.000000000751 = 7.51 x 10-10 Since you need to move the decimal point 10 places to the right, the exponent of 10 will be -10. What really you are doing is you are multiplying the given number by 1 represented as 1010/1010 : 0.000000000751 x 1010/1010, where 1/1010 = 10-10.
3.5 X 1010 .
I would write is 3.1008 x 1010 But it could be expanded to 3.100809003 x 1010
It is 1*1010 metres, or simply 1010 metres.
