Place the numbers in descending order.
2.3 × 10^−10 ; 3.2 × 10^−10 ; 2.3 × 10^−12 ; 2.3 × 10^−8
(2 points)
___; ___; ___; ___;
3.2 × 10^−10; 2.3 × 10^−10; 2.3 × 10^−8; 2.3 × 10^−12
To place the numbers in descending order, we compare the exponents first, and then the mantissas (coefficients).
2.3 × 10^−12 ; 2.3 × 10^−10 ; 2.3 × 10^−8 ; 3.2 × 10^−10
To place numbers in descending order, we need to compare the values of each number.
Let's first compare the exponents of the given numbers.
The exponents are -10, -10, -12, and -8.
Since negative exponents indicate very small values, the higher the negative exponent, the larger the value. Therefore, we can conclude that:
2.3 × 10^(-12) < 2.3 × 10^(-10) < 3.2 × 10^(-10) < 2.3 × 10^(-8)
Now, let's rearrange the numbers in descending order:
2.3 × 10^(-8), 3.2 × 10^(-10), 2.3 × 10^(-10), 2.3 × 10^(-12)
So, the correct order is:
2.3 × 10^(-8); 3.2 × 10^(-10); 2.3 × 10^(-10); 2.3 × 10^(-12).
