which number is irrational?
a:0.3
B:sqrt5
C:0.454545...
D:0.777...
I believe choice D is the correct answer.
Irrational means it repeats infinitely, but not in repeating blocks, so I believe choice (B) is the answer.
Any terminating or repeating decmal can aways be written as a rational number
The square root of any non-square will always be irrational
So....tertre is correct
