Answer:
To write the Hindu-Arabic numeral 872 as a Babylonian numeral using the symbols I and <, we need to break it down into its place values:
The digit 8 is in the hundreds place.
The digit 7 is in the tens place.
The digit 2 is in the ones place.
To represent 800 in the hundreds place, we use 8 symbols <. To represent 70 in the tens place, we use 7 symbols < followed by 1 symbol I. To represent 2 in the ones place, we use 2 symbols I.
Putting these symbols together, we get the Babylonian numeral:
<<<<< <<<< <<<< <<<< IIII
So, the Babylonian numeral equivalent of the Hindu-Arabic numeral 872 is <<<<< <<<< <<<< <<<< IIII.
