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

A=6.2x10^-5; B=12.3x10^-7; C=5.2x10^3; D=3.7x10^5

B, A, C, D

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

First, let's rewrite the numbers in standard form:

A = 0.000062
B = 0.00000123
C = 5200
D = 370000

Now, let's compare the numbers starting with the exponents:

B < A < C < D

Next, let's compare the coefficients within each group:

For A and B: B < A
For A and C: C < A
For A and D: A < D
For B and C: C < B
For B and D: B < D
For C and D: C < D

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

B < A < C < D

Thus, the correct order is:

B, A, C, D
