The Radix Economy of a number in a particular base is the number of digits needed to express it in that base, multiplied by the base. In functional form we write: 
, where E is the radix econony, b and N, are the base and number, respectively, and 
, is the number of digits of the base-b representation of N.
, where E is the radix econony, b and N, are the base and number, respectively, and , is the number of digits of the base-b representation of N.For example, if 
and 
, then the radix economy is 
:
and , then the radix economy is : >> E = 2 * length(dec2bin(1000))
>> E =
20
Given a base b, and an integer n, calculate 
, for 
.
, for .For example, if 
and 
, we have:
and , we have: >> F = 3 * length(dec2base(factorial(10),3))
>> F =
42

NOTE: As it is, this problem is quite simple. In fact, a solution is already given for small values of b and n. Therefore, to make it a bit interesting, some built-in functions are disabled.
