what is the order of the numbers from least to greatest?

A= 1.5 x 10^3 B = 1.4 x 10^-1 C = 2 x 10^3 D 1.4 x 10 ^-2

D = 1.4 x 10^-2, B = 1.4 x 10^-1, A = 1.5 x 10^3, C = 2 x 10^3.

The order from least to greatest is D, B, A, C.

To find the order of the numbers from least to greatest, we can compare the exponents first.

1.4 x 10^-2 has the smallest exponent, followed by 1.4 x 10^-1.

Next, we compare the coefficients:

1.4 x 10^-2 < 1.4 x 10^-1

The next two numbers have the same exponent (10^3), so we compare the coefficients again:

1.5 x 10^3 > 2 x 10^3

Putting it all together, the order from least to greatest is:

1.4 x 10^-2, 1.4 x 10^-1, 1.5 x 10^3, 2 x 10^3

To determine the order of the given numbers from least to greatest, we need to compare the exponents and the values of the numbers.

Let's start by comparing the exponents:
- B has the smallest exponent (-1) since it is a negative exponent.
- D has the next smallest exponent (-2).
- A and C have positive exponents (3), with C having the larger value in front.

Now, let's compare the values of the numbers:
- B has a value of 1.4.
- D has a value of 1.4 (same as B, but with a smaller exponent making it smaller in value).
- A has a value of 1.5.
- C has a value of 2.

Putting it all together, let's arrange the numbers from least to greatest:
1. B = 1.4 x 10^-1
2. D = 1.4 x 10^-2
3. A = 1.5 x 10^3
4. C = 2 x 10^3

Thus, the order of the numbers from least to greatest is B, D, A, C.
