The Richter scale is used to measure the magnitude of an earthquake. The
magnitude, R, is given by the equation R = 0.65log(0.39 €) +1.45, where Eis the
energy (measured in kilowatt-hours) released by the earthquake. Determine the
amount of energy released by an earthquake of magnitude 7.5.
Rewrite the equation for the magnitude of an earthquake, using the
magnitude of 7.5 given in the problem.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
