From the starting point of 70000000000.0, shift 10 decimal places to the left, so the exponent for base 10 is 10. Therefore, 70000000000 in scientific notation is 7 x 1010
10x 10 is Base & x is exponent
0.0000009 in Scientific Notation = 9 x 10-7
9^6
It is 2.5/(10*10*10*10) or 2.5*0.0001
An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
The answer is 4.71*10^-7.
