Ah, converting numbers into scientific notation is like painting a happy little tree. To convert 0.0000008 into scientific notation, you move the decimal point to the right until there is only one non-zero digit to its left. In this case, it becomes 8 x 10^-7. Just like that, you've created a beautiful scientific notation masterpiece!
It is 8.9*10^-5 in scientific notation
It is: 3.32*10^-3 in scientific notation
It is: 1.95*10^14 in scientific notation
1,000,000 in Scientific Notation = 1 x 106
1,550 in Scientific Notation = 1.55 x 103
It is 8.9*10^-5 in scientific notation
It is: 3.32*10^-3 in scientific notation
Due to the leading zeros I guess there is a missing decimal point after/before the first zero: 0.0000008 = 8×10^-7 .00000008 = 0.00000008 = 8×10^-8
It is: 1.95*10^14 in scientific notation
1,550 in Scientific Notation = 1.55 x 103
1,000,000 in Scientific Notation = 1 x 106
1,000,000 in Scientific Notation = 1 x 106
150,000,000 in Scientific Notation = 1.5 x 108
9.16 in Scientific Notation = 9.16 x 100
It is: 3.9*10^7 in scientific notation
251,000,000 in Scientific Notation = 2.51 x 108
0.002378 in Scientific Notation = 2.378 x 10-3
