Question

will fan and medal !!
suppose that volumes of four stars in the Milky Way ( Mikey Way lmao ) are 2.7 x 10^18 km^3, 6.9 x 10^12 km^3, 2.2 x 10^12 km^3, and 4.9 x 10^21 km^3. what is the order of the stars from least to greatest volume?
- 2.7 x 10^18, 6.9 x 10^12, 4.9 x 10^21, 2.2 x 10^12
- 2.2 x 10^12, 6.9 x 10^12, 2.7 x 10^18, 4.9 x 10^21
- 2.7 x 10^18, 6.9 x 10^12, 2.2 x 10^12, 4.9 x 10^21
- 2.2 x 10^12, 4.9 x 10^21, 2.7 x 10^18, 6.9 x 10^12

Answer 1

Look at the order of the volumes. For example a star with a volume of an order of \(10^{21}\) is far more greater than an order of \(10^{12}\).

Answer 2

The correct answer is - 2.2 x 10^12, 6.9 x 10^12, 2.7 x 10^18, 4.9 x 10^21 (option 3rd ). Help to help you again. Thank you

Answer 3

It's not worth it if he doesn't put in the effort. We don't hand out answers here, we try to guide the person to it.

Answer 4

We need look the exponent. so we will order like,
2.2 x 10^12, 6.9 x 10^12, 2.7 x 10^18, 4.9 x 10^21

But here the exponent of 10 in 2.2 x 10^12 and 6.9 x 10^12 is same. So, then we compare number 2.2 and 6.9. Here, 2.2 < 6.9 so 2.2 x 10^12 < 6.9 x 10^12

Thus, our correct answer is:
2.2 x 10^12, 6.9 x 10^12, 2.7 x 10^18, 4.9 x 10^21
