Complete step-by-step answer:
Numbers in this system are represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, are based on seven symbols:

We need to find the corresponding Hindu-Arabic numerals for \[{\text{CLXXII}}\].
So we can get the value of the symbol \[C\,\& \,L\].
The value of \[{\text{C & L}}\] are \[100\,\&\, 50\] respectively.
The value of \[{\text{X}}\] is \[10\] and \[{\text{II}}\] is \[2\].
So \[{\text{CLXXII}}\] corresponds to
\[100 + 50 + 10 + 10 + 2 = 172\]
The corresponding Hindu-Arabic numerals for \[{\text{CLXXII}}\] is \[172\].
