2.49 x 10 and -2 less or greater then 2.49 x 10 and -3
To compare 2.49 x 10^2 and 2.49 x 10^3, we can compare the exponents.
Since 10^3 is a larger exponent than 10^2, that means 2.49 x 10^3 is greater than 2.49 x 10^2.
Similarly, to compare -2.49 x 10^2 and -2.49 x 10^3:
Since 10^3 is a larger exponent than 10^2, that means -2.49 x 10^3 is less than -2.49 x 10^2.
To determine if 2.49 x 10^(-2) is less than or greater than 2.49 x 10^(-3), we need to compare the exponents (-2 and -3) and see which is smaller.
Since the exponent -2 is greater than -3, we can conclude that 2.49 x 10^(-2) is greater than 2.49 x 10^(-3).
To determine whether 2.49 x 10^(-2) is less than or greater than 2.49 x 10^(-3), we can compare the exponents since the base (2.49) is the same in both cases.
In scientific notation, raising a number to a negative power makes it smaller. Therefore, a larger negative exponent results in a smaller value.
In this case, -2 is a larger negative exponent compared to -3, which means that 2.49 x 10^(-2) is larger (greater) than 2.49 x 10^(-3).
