SUMMARY

The discussion focuses on determining the base of a numeral system where the number 121 in an unknown base equals the decimal number 324. It is established that 121 in base b can be expressed as 1*b^2 + 2*b + 1. To solve for the base, one must set the equation 1*b^2 + 2*b + 1 = 324 and find the value of b. This mathematical problem illustrates the relationship between different numeral systems and the conversion process between them.

Base of the system problems, please help

What is the base of the system in which 121 represents the same number as the decimal number 324?






I need someone to tell what this thing is saying thank you.

The base of the system is referring to base of the number system. i.e. base 2 is binary and base 10 is the decimal system that we usually use.

It is telling you that 324 is a decimal number so it is the normal numbers you work with, but 121 is not. You need to find what base it is in.
 
If b is the base, then 121 (base b) represents 1*b^2 + 2*b + 1, which has to equal 324 (base 10).
 
many thanks to both of u
