Question

has the rational number 441/2² x 5² x 7² a terminating or a non- terminating decimal representation?​

Answer 1

$\Large\mathtt\green{ ☘︎ \: }\huge\underline\mathtt\red{Answer : }$

Then, x has a decimal expression which is non-terminating repeating. This is clear that the prime factorization of the denominator is not of the form 2 n × 5m.

Hence, it has terminating decimal expansion.
