Here is the formula:
#M=log(I/s)#
Earthquake 1:
#8=log(I_1/s)#
#10^8=I/s#
#I=10^8s#
Earthquake 2:
#4=log(I_2/s)#
#10^4=I/s#
#I=10^4s#
To determine how many time one earthquake is more intense than the other we use this:
#(I_1s)/(I_2s)#
#(10^8s)/(10^4s)#
#10^8/10^4=10^4# or 10000 more times intense.
Therefore an earthquake with a magnitude of 8 is not twice the intensity of an earthquake with a magnitude of 4.

How is the intensity of an earthquake with magnitude 8 not twice the intensity of an earthquake with magnitude 4?

the answer to
A polynomial function #p# can be factored into seven factors: #( x-3), ( x+1)#, and 5 factors of #(x -2)#. What are its zeros with multiplicity, and what is the degree of the polynomial? Explain.
