The problem is that 7^2 is 7*7, and the same for 8^2. The right answer is the square root of 15, or 3.87

Use the GCF to write it as a distributive property
First, we find the GCF of 75 and 45


The common factor is:


So,
becomes

<em>Hence, the sum has been rewritten as </em>

For this sort of problem, you need to be familiar with prefixes.
So:
megabyte =
bytes
kilobyte =
bytes
and a regular byte would just be 
Now, you will need to do a conversion:

I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are
bytes!)
In the second fraction thought, remember one kilobyte is
bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do
, but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
kilobytes (1000 kilobytes)

Earthquakes can cause all of the above.
trigger other earthquakes - when there is a large magnitude earthquake it
lead to shake the earth's surface. Thus it can create more earthquakes on the same place or neighboring places.
cause billions of dollars - when there is a large disturbance it can destroy big buildings, homes, etc. Which is basically a billion dollar loss.
cause tsunami - If there is a disturbance in the earth's surface near sea's, etc there is chance of tsunami.
