If the exponent is not negative, then a number written in scientific notation is greater than or equal to 1.
It is: 5.08*10^8 in scientific notation and the exponent of 10 is 8
The absolute value is greater than or equal to 1.
5
21 can be written as 2.10 × 101
In standard form, a number is expressed in a way that it can be either greater than or equal to one or less than one. If the number is greater than or equal to one, it will have a positive exponent when converted to scientific notation (e.g., 5000 becomes (5.0 \times 10^3)). Conversely, if the number is less than one, it will have a negative exponent (e.g., 0.005 becomes (5.0 \times 10^{-3})). Thus, the position of the decimal point in relation to the number one determines the sign of the exponent in scientific notation.
If a number larger than 1 is converted to scientific notation, the exponent is positive. This is because the decimal point is moved to the left to express the number in the form of ( a \times 10^n ), where ( a ) is between 1 and 10, and ( n ) indicates how many places the decimal was moved. For example, the number 5000 in scientific notation is written as ( 5.0 \times 10^3 ).
When 508,000,000 is written in scientific notation, it becomes 5.08 × 10^8. The value of the exponent in this case is 8. This indicates that the decimal point has been moved 8 places to the left to convert the number into its scientific notation form.
Do you mean how is it written in scientific notation? 1.01 X 10^6.
The value is 8 because the exponent written in scientific notation is 2.45x10^8, which means 2.45 times 10 to the eighth power.
0.0045 = 4.5 x 10-3
The sign of the exponent for a number written in scientific notation depends on whether it is a whole number or a fraction. 40 is 4 x 101 0.4 is 4 x 10-1
