Place the numbers in descending order.
2.3 x 10^-10; 3.2 x 10^-10; 2.3 x 10-12; 2.3 x 10^-8
3.2 x 10^-10; 2.3 x 10^-10; 2.3 x 10^-8; 2.3 x 10^-12
To place the numbers in descending order, you need to compare their values.
First, let's compare the powers of 10:
-2 (from 10^-2)
-8 (from 10^-8)
-10 (from 10^-10)
-12 (from 10^-12)
The numbers with the smallest power of 10 is 10^-12, followed by 10^-10, then 10^-8, and finally 10^-2.
Now let's compare the numbers themselves:
2.3 x 10^-12
2.3 x 10^-10
2.3 x 10^-8
Since the coefficient (2.3) is the same for all the numbers, we compare the powers of 10.
Again, the number with the smallest power is 2.3 x 10^-12, followed by 2.3 x 10^-10, and finally 2.3 x 10^-8.
So, the numbers in descending order are:
2.3 x 10^-12
2.3 x 10^-10
2.3 x 10^-8
10^-2
To place the numbers in descending order, we need to compare the exponents first. The smaller the exponent, the larger the number.
Let's compare the exponents first:
2.3 x 10^-10
3.2 x 10^-10
2.3 x 10^-12
2.3 x 10^-8
Comparing the exponents, we can see that 10^-12 is the smallest exponent. So, the next step is to compare the numbers themselves:
2.3 x 10^-10
3.2 x 10^-10
2.3 x 10^-8
Comparing the numbers, we can see that 3.2 x 10^-10 is the largest.
Now, we have two numbers left to compare:
2.3 x 10^-10
2.3 x 10^-8
Since the exponent is the same, we can compare the coefficients. In this case, 2.3 x 10^-8 is larger than 2.3 x 10^-10.
Therefore, the numbers in descending order are:
3.2 x 10^-10
2.3 x 10^-8
2.3 x 10^-10
2.3 x 10^-12
