Question

the decimal expansion of 129/2^2*5^7*7^5​ will be
(a) terminating
(b)non-terminating
(c) non-terminating repeating
(d) non-terminating non repeating​

Answer 1

Answer:

Step-by-step explanation:

Non terminating decimal expansion because the denominator have LCM 2,5as well as 7. If there were only 2and 5,only 2,only 5 then terminating.

Hope helped you.

Answer 2

Option b - non-terminating

Step-by-step explanation:

Given : Decimal expansion $\frac{129}{2^2\times 5^7\times 7^5}$

To find : The decimal expansion will be ?

Solution :

If the decimal expansion denominator is in the form $2^m\times 5^n$ then it is terminating and if not then it is non-terminating.

In the decimal expansion $\frac{129}{2^2\times 5^7\times 7^5}$ the denominator also have multiple of 7.

So, the given decimal expansion is non-terminating.

Therefore, option b is correct.
