Answer
Arthashastra is not a work by Brahmagupta. Brahmagupta was an Indian mathematician and astronomer who lived in the 6th century CE. He is known for his contributions to mathematics, including the development of the decimal number system and the invention of the zero. Arthashastra, on the other hand, is a treatise on statecraft and economics written by Kautilya in the 4th century BCE.
