Question
Without actual division show that each of the following rational numbers is a non-terminating repeating decimal
(i) `73/(2^3× 3^3 × 5)`
Solution
`73/(2^3× 3^3 × 5)`
We know 2, 3 or 5 is not a factor of 73, so it is in its simplest form.
Moreover, (22× 33 ×5) ≠ (2m × 5n)
Hence, the given rational is non-terminating repeating decimal.
