If the number in sci. notation has a positive exponent, move the decimal to the right the same number of spaces as the exponent's number.
For example: 5.78 x 103 = 5780
If the exponent is negative, move the decimal to the left the same number of spaces as the exponent's number.
For example: 2.945 x 10-5 = 0.00002945

to convert scientific notation to decimal you count the number of spaces up to the last digit then put the decimal point then put x10 to the power of if how many places you move the decimal point.................................
Scientific notation is a way to express either a very large, or a very small number.10x5.34 is an example of scientific notation. So, move the decimal point to the right (since there is a positive exponent). It then becomes 53,000.If there is a negative exponent, move the decimal point to the left instead of the right. 10x4.6-3 would become 0.0046.
251,000,000 in Scientific Notation = 2.51 x 108
Scientific notation is a way of expressing numbers as a coefficient multiplied by a power of 10. To convert 367.666 km into scientific notation, we move the decimal point to the left until there is only one non-zero digit to its left. This gives us 3.67666 x 10^2 km, where 10^2 represents the number of decimal places we moved the decimal point.
To convert 156% to decimal notation divide by 100: 156% ÷ 100 = 1.56
