Answer:
Step-by-step explanation:
0.144 rational
√(0.144) irrational
√(0.0144)=0.12 rational
1st digit: 9 possibilities (can’t have 0)
2nd digit: 10 possibilities
3rd digit:10
4th digit:10
5th digit:10
6th digit: 4 possibilities (it can only be even)
9•10•10•10•10•4 =360,000 possibilities
I think the answer is 3 but I’m not sure.
Hope this helps!
