1. The units digit of $$(n10^2)$$ is 7
2. The thousands digit of $$(n10^4)$$ is7

I think n should be replaced by x

Let x = 0.abcd

Tenths digit is a
Hundredths is b

If x*10^2 = 7
That means 0.abcd = ab.cd
B is the units digit and that equals 7.

Sufficient.

Now for statement 2)
0.abcd * 10^4 = abcd

That means a is 7. We are not looking for a rather we are looking for b.

Insufficient.

That makes so much sense thank you SO VERY MUCH! I think my issue was being unable to think mentally of x as 0.abcd
