This is the basic and conceptual question from real numbers chapter in which we have given a rational number 129/(2²×5³×7²) and we have to prove that the given rational number is a non terminating decimal.
Kindly solve the above problem in detail
RS Aggarwal, Class 10, chapter 1C, question no 2(iii)
129/(2²×5³×7²)
2,5 or 7 is not factor of 129 so fraction is in its simplest form.
and, (2^2×5^7×7^5)≠(2^m×5^n) in denominator
hence given fraction is non -terminating repeating decimal.
