Place the numbers in descending order.
2.3 × 10^−10 ; 3.2 × 10^−10 ; 2.3 × 10^−12 ; 2.3 × 10^−8

3.2 × 10^−10 ; 2.3 × 10^−10 ; 2.3 × 10^−8 ; 2.3 × 10^−12
In order to place the numbers in descending order, we need to compare the exponents first and then compare the coefficients.
Comparing the exponents:
10^-12 < 10^-8 < 10^-10
Comparing the coefficients:
2.3 < 3.2
Now, let's put them in descending order:
3.2 × 10^-10;
2.3 × 10^-10;
2.3 × 10^-12;
2.3 × 10^-8
To place the numbers in descending order, we need to compare their values. However, in this case, the numbers are written in scientific notation, which means we need to first convert them into standard form.
To convert a number from scientific notation to standard form, we take the coefficient (the number before the × 10^) and multiply it by the power of 10 (the number after the ^) and remove the × 10^ part.
Let's convert each number:
2.3 × 10^−10 = 0.00000000023
3.2 × 10^−10 = 0.00000000032
2.3 × 10^−12 = 0.0000000000023
2.3 × 10^−8 = 0.000000023
Now, we can compare these numbers and place them in descending order:
0.000000023, 0.00000000032, 0.00000000023, 0.0000000000023
So, in descending order, the numbers are:
0.000000023
0.00000000032
0.00000000023
0.0000000000023
