You scientific notation determine which of these numbers has the least value $123,893 31,892 or 12,786 write your answer in scientific notation Express to the exact decimal place

To determine which number has the least value, we can rewrite all the numbers in scientific notation.

$123,893 = 1.23893 \times 10^5$
$31,892 = 3.1892 \times 10^4$
$12,786 = 1.2786 \times 10^4$

Comparing the exponents, we can see that $3.1892 \times 10^4$ has the least value.

To determine which of these numbers has the least value, let's convert them into scientific notation:

$123,893 = $1.23893 x 10^5
31,892 = 3.1892 x 10^4
12,786 = 1.2786 x 10^4

Comparing the numbers in scientific notation, we can see that $1.23893 x 10^5 has the least value, as it has the highest exponent value.

To determine which of these numbers has the least value, we can convert all of them to scientific notation and compare their exponents.

Let's start with the first number, $123,893.

To write this number in scientific notation, we need to move the decimal point to the right until only one digit remains before the decimal.

In this case, we obtain $1.23893 × 10^5.

Now let's work on the second number, $31,892.

We can follow the same steps as above, moving the decimal point to the right until only one digit remains before the decimal.

This gives us $3.1892 × 10^4.

Lastly, let's convert the third number, 12,786.

Again, we move the decimal point until we have one digit before the decimal.

This results in 1.2786 × 10^4.

Now, looking at the exponents, we see that the second number, $3.1892 × 10^4, has the smallest exponent. Therefore, it has the least value among the given numbers.
