Answer:

After four places the decimal form of  \frac{125}{2^4\times5^3} will terminate.

Step-by-step explanation:

Given,   \frac{125}{2^4\times5^3}....(1)

Now we try to expand equation (1)

considering the decimal part

{2^4\times5^3} = (2 × 2 × 2 × 2) × (5 × 5 × 5)

{2^4\times5^3} = (16) × (125)

{2^4\times5^3} = 2000

Hence the value in the denominator is 2000.

Now we try to solve numerator and denominator.

i.e.   \frac{125}{2000}.

= 0.0625

And as we can count there are four numbers after the decimal (0, 6, 2, 5)

Therefore, after four places the decimal form of  \frac{125}{2^4\times5^3} will terminate.
