Place these numbers from 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 these numbers in descending order, we need to compare the magnitude of the numbers, disregarding the exponential part.
Let's compare the numbers without the exponential part:
2.3, 3.2, 2.3, 2.3
To determine the descending order, we start from the highest value and move to the lowest.
Since all the numbers have the same whole part, 2.3, we need to compare the decimal parts.
Comparing the decimal parts:
0.3, 0.2, 0.3, 0.8
The decimal parts are 0.3, 0.2, 0.3, and 0.8.
Now we can arrange them in descending order:
2.3 X 10^-8 (0.8)
3.2 X 10^-10 (0.2)
2.3 X 10^-10 (0.3)
2.3 X 10^-12 (0.3)
Hence, the numbers in descending order are:
2.3 X 10^-8, 3.2 X 10^-10, 2.3 X 10^-10, 2.3 X 10^-12
To place these numbers in descending order, we need to compare the magnitude of the numbers by looking at their exponent values.
1. 2.3 X 10^-10
2. 3.2 X 10^-10
3. 2.3 X 10^-12
4. 2.3 X 10^-8
Comparing the exponent values, we can see that:
10^-12 < 10^-10 < 10^-8 < 10^-8
Now, let's compare the coefficients (the numbers before the "X") for the numbers that have the same exponent:
1. 2.3 X 10^-10
2. 3.2 X 10^-10
Since the exponent is the same, we compare the coefficients:
2.3 < 3.2
The final descending order is:
3.2 X 10^-10 > 2.3 X 10^-10 > 2.3 X 10^-12 > 2.3 X 10^-8
And thats in decending order?
Apologies for the confusion. Let's arrange the numbers in descending order correctly:
1. 3.2 X 10^-10
2. 2.3 X 10^-10
3. 2.3 X 10^-8
4. 2.3 X 10^-12
The correct descending order is:
3.2 X 10^-10 > 2.3 X 10^-10 > 2.3 X 10^-8 > 2.3 X 10^-12
