Problem Solution:

In this program, we will read an integer number and base to calculate logarithm from the user using gets.chomp.to_i. Then we will calculate the logarithm of a given number based on the given base using the Math.log() function.

Program/Source Code:

The source code to calculate the logarithm of a given number based on a given base is given below. The given program is compiled and executed successfully.

# Ruby program to calculate the logarithm 
# of a given number based on a given base

print "Enter Number: ";
num = gets.chomp.to_i;  

print "Enter Base: ";
base = gets.chomp.to_i;  


result = Math.log(num,base);

print "Result is: ",result;

Output:

Enter Number: 124
Enter Base: 2
Result is: 6.954196310386876

Explanation:

In the above program, we read an integer number and base for logarithm from the user using gets.chomp.to_i and calculated the logarithm based on the given base of input number using Math.log() function printed the result.
