5. Suppose that the volumes of four stars in the Milky Way are 2.7 × 1018 km3, 6.9 × 1012 km3, 2.2 × 1012 km3, and 4.9 × 1021 km3. What is the order of the stars from least to greatest volume?

A.) 2.7 × 1018 km3, 6.9 × 1012 km3, 4.9 × 1021 km3, 2.2 × 1012 km3

B.) 2.2 × 1012 km3, 6.9 × 1012 km3, 2.7 × 1018 km3, 4.9 × 1021 km3

C.) 2.7 × 1018 km3, 6.9 × 1012 km3, 2.2 × 1012 km3, 4.9 × 1021 km3

D.) 2.2 × 1012 km3, 4.9 × 1021 km3, 2.7 × 1018 km3, 6.9 × 1012 km3

I have no idea what the answer is. Please help.
Thank You.

To find the order of the stars from least to greatest volume, you need to compare the volumes of the stars provided.

The volumes provided are:
Star 1: 2.7 × 10^18 km^3
Star 2: 6.9 × 10^12 km^3
Star 3: 2.2 × 10^12 km^3
Star 4: 4.9 × 10^21 km^3

To make the comparison easier, let's write the volumes in scientific notation:

Star 1: 2.7 × 10^18 km^3
Star 2: 6.9 × 10^12 km^3
Star 3: 2.2 × 10^12 km^3
Star 4: 4.9 × 10^21 km^3

To compare the volumes, you need to consider the exponent first. The star with the greatest exponent will have the largest volume.

Comparing the exponents:
Star 1: 10^18
Star 2: 10^12
Star 3: 10^12
Star 4: 10^21

From the comparison, we can see that Star 4 has the greatest exponent, indicating the largest volume.

Now, let's compare the coefficients (the numbers in front of the exponent):

Star 1: 2.7
Star 2: 6.9
Star 3: 2.2
Star 4: 4.9

Comparing the coefficients:
Star 1: 2.7
Star 2: 6.9
Star 3: 2.2
Star 4: 4.9

From the comparison, we can see that Star 2 has the largest coefficient, indicating the second-largest volume.

Therefore, the order of the stars from least to greatest volume is:
Star 3, Star 1, Star 2, Star 4.

So, the correct answer is C.) 2.7 × 10^18 km^3, 6.9 × 10^12 km^3, 2.2 × 10^12 km^3, 4.9 × 10^21 km^3.

suppose that the volumes of four stars in the milky way are 2.7x10^8 km^3, 6.9x10^4 km^3, 2.2x10^12 km^3, and 4.9x10^12 km^3. what is the order of the stars from least to greatest volume?

exponents in this forum are indicated with the ^ symbol

So I am sure you meant
2.7x10^18 etc

The larger the exponent, the larger the number
If two numbers are have the same power of 10, then look at the factor in front to tell which is larger
e.g.
2.2x10^12 < 6.9x10^12

I am sure you can now sort them according to size
