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.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,
