on the richter scale , which measures the total amount of energy released during an earthquake , a reading of x - 1 indicates one - tenth the released energy as is indicated by a reading of x . on that scale , the frequency corresponding to a reading of 9 is how many times as great as the frequency corresponding to a reading of 3 ?
"if richter scale reading goes from x - 1 to x it will be 10 if richter scale reading goes from 3 to 4 it will be 10 if richter scale reading goes from 4 to 5 it will be 10 if richter scale reading goes from 5 to 6 it will be 10 similarly if richter scale reading goes from 6 to 7 it will be 10 and if richter scale reading goes from 7 to 8 it will be 10 and if richter scale reading goes from 8 to 9 it will be 10 so it will from 3 to 9 i . e 4,5 , 6,7 , 8,9 = 10 * 10 * 10 * 10 * 10 * 10 = 10 ^ 6 answer is e"
power(const_10, subtract(9, 3))
