What is the order of 1.5x10 ^ 3,1.4x10-1,2x10 ^3, and 1.4 x 10-2 from least to greatest?

Let's list the choices.

1.5x10^3
1.4x10-1
2x10 ^3
1.4 x 10-2

First, you look at the exponent of 10. The positive exponent of 10 will always be larger than the negative because the decimal point moves to the right, increasing its value. The greatest is 10^3. Between these two, the greater one is 2 followed by 1.5.

For the negative exponents of 10, 10^-2 is lesser than 10^-1.

Thus, if you arrange from least to greatest:

1.4 x 10-2  <  1.4x10-1   <    1.5x10 ^ 3   <   2x10 ^3

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
