Question

Our galaxy, the Milky Way, has a diameter of about 1x10^21 meters.the largest galaxy known to man, the IC 1101, has a diameter of 5x10^22 meters. The diameter of the IC 1101 is about how many times greater than the diameter of the Milky Way ?

Answer 1

The diameter of the IC 1101 galaxy is approximately 50 times greater than the diameter of our Milky Way galaxy.

Step-by-step explanation:

The student asked how many times greater the diameter of the largest known galaxy, IC 1101, is compared to the diameter of our Milky Way galaxy.

We can calculate this by dividing the diameter of IC 1101 by the diameter of the Milky Way.

1. 
   
3. Diameter of IC 1101 = 5x1022 meters
4. 
   
6. Diameter of the Milky Way = 1x1021 meters
7. 
   
9. Divide the diameter of IC 1101 by the diameter of the Milky Way: (5x1022) / (1x1021)

When we divide these two numbers, we're essentially subtracting the exponents because the bases are the same (10).

5x1022 / 1x1021 = 5x10(22-21) = 5x101 = 50

Therefore, the diameter of IC 1101 is approximately 50 times greater than the diameter of the Milky Way.
