Question

Log rithm chapter class 9th

Answer 1

A logarithmic function is the inverse of an exponential function. 

Exponential functions – The y value increases more rapidly as the value of x increases.

Logarithmic functions – The y value increases lessrapidly as the value of x increase.

There are many applications of logarithms, but one of the most familiar is measuring earthquakes on the Richter scale. This is extremely useful, because the logarithmic scale allows use to measure earthquakes which can vary drastically in intensity. The logarithmic scale has a very small range (1-10) despite wide ranging intensity of all earthquakes. Each one point increase on the Richter scale means the earthquake is 10 times more powerful.  An earthquake measured at 6.0 on the Richter scale is considered strong. However, 6.0 quakes pale in comparison to a 7.0 quake (which is 10x stronger) or an 8.0 quake (which is 100x stronger).
