find the cube root of a number in ruby

To find the cube root of a number in Ruby, you can use the Math.cbrt method. This method takes the input number as an argument and returns the cube root of the number. Here's an example:


main.rb
num = 125
cube_root = Math.cbrt(num)

puts "The cube root of #{num} is #{cube_root}."
86 chars
5 lines

Output:


main.rb
The cube root of 125 is 5.0.
29 chars
2 lines

You can also use the exponent operator **** to find the cube root, like this:


main.rb
num = 125
cube_root = num**(1.0/3)

puts "The cube root of #{num} is #{cube_root}."
84 chars
5 lines

Output:


main.rb
The cube root of 125 is 5.0.
29 chars
2 lines
