JavaScript ERROR

[YahyaBourouina]

chatGPT sent me a red message when i hover it, it show this:
ParseError: KaTeX parse error: Expected 'EOF', got '_' at position 17: ...00 < \text{what_to_type_here}

It's possible that there is a missing or misplaced closing delimiter, or an unsupported character or symbol in that portion of the expression.
