2.3 x 10^-10 or 2.3 x 10^-8
Which is greater
2.3 x 10^-8 is greater.
To determine which number, 2.3 x 10^-10 or 2.3 x 10^-8, is greater, we can compare their exponents.
In scientific notation, a smaller exponent indicates a larger number. So, 10 raised to the power of -8 is greater than 10 raised to the power of -10.
Therefore, 2.3 x 10^-8 is greater than 2.3 x 10^-10.
To determine which value is greater, we need to compare the exponents of the scientific notation.
In this case, 10^-10 is smaller than 10^-8 because the exponent -8 is larger than -10. Therefore, 2.3 x 10^-8 is greater than 2.3 x 10^-10.
