Khan academy anyone can help me plz on this

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.

How do you solve a question like this?

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
