Factories the given expression and divide them: 45y^3(y^2 + 2y - 48) / 30y^2 (y^2 - 64)

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
