Answer:
7^3/5^4 is terminating decimal expansion
Step-by-step explanation:
By the theorm that if x is a rational number if it can be expressed in form p/q and q≠zero. So the decimal expansion of q will be in the power of 2^n5^m ( read theorem 1.5 ncert).
So by the above explanation, we can say that,
= 7³×2⁴/5⁴×2⁴
= 7³×2⁴/10⁴
= 343×16/10000
= 5488/10000
=0.5488 is the answer
mark me brainliest only if you find it helpful. I suggest you read all examples in ncert.
