place the numbers descending order.
2.3* 10^-10 ; 3.2 *10^-10 ;2.3 * 10^-12 ;2.3* 10^-8
The numbers in descending order are as follows:
3.2 * 10^-10
2.3 * 10^-10
2.3 * 10^-12
2.3 * 10^-8
To arrange the numbers in descending order, we compare the values of the numbers.
The given numbers are:
2.3 * 10^-10
3.2 * 10^-10
2.3 * 10^-12
2.3 * 10^-8
First, let's look at the exponential part. All the numbers have the same base (10), so we can focus on the coefficient (the number before the multiplication factor).
Comparing the coefficients of the given numbers, we have:
3.2 (largest)
2.3
2.3
2.3 (smallest)
Now, let's compare the exponential parts (the exponents):
Comparing the exponential parts, we have:
10^-10
10^-10
10^-12
10^-8 (largest)
Putting it all together, we can arrange the numbers in descending order:
3.2 * 10^-10 (largest)
2.3 * 10^-10
2.3 * 10^-12
2.3 * 10^-8 (smallest)
So, the numbers in descending order are:
3.2 * 10^-10
2.3 * 10^-10
2.3 * 10^-12
2.3 * 10^-8
To place the numbers in descending order, we will compare the values of the numbers.
The given numbers are:
2.3 * 10^-10
3.2 * 10^-10
2.3 * 10^-12
2.3 * 10^-8
Let's compare the first two numbers:
2.3 * 10^-10 vs 3.2 * 10^-10
Since both numbers have the same power of 10, we can compare the decimal parts. In this case, 3.2 is greater than 2.3.
So, the first number in our descending order list is 3.2 * 10^-10.
Now, let's compare the next number with the current highest number:
2.3 * 10^-12 vs 3.2 * 10^-10
Since the power of 10 in the first number is smaller than the power of 10 in the second number, we can directly say that the second number is greater.
So, the next number in our descending order list is 2.3 * 10^-10.
Finally, let's compare the last number with the current highest number:
2.3 * 10^-8 vs 2.3 * 10^-10
Again, since the power of 10 in the first number is larger than the power of 10 in the second number, we can directly say that the first number is greater.
So, the last number in our descending order list is 2.3 * 10^-8.
In conclusion, the numbers in descending order are:
3.2 * 10^-10
2.3 * 10^-10
2.3 * 10^-8
