An irrational number/value is one you cannot express in terms of a ration, or a fraction, it cannot be written as fraction
now 291.87... is simple, two decimals, so you use two zeros at the botom and end up with
and boom, there you are, a fraction, nice and dandy
now, let's see the first one -√(127) well, low and behold, 127 is a prime number, and and thus is has no two factors that'd serve as root, so, there's no rational root that'd give that, that makes it irrational

Answer:
a) Q(-2,1) is false
b) Q(-5,2) is false
c)Q(3,8) is true
d)Q(9,10) is true
Step-by-step explanation:
Given data is is predicate that
then
. where
are rational numbers.
a)
when
Here that is
satisfied. Then
this is wrong. since
That is Thus
is false.
b)
Assume .
That is
Here that is
this condition is satisfied.
Then
this is not true. since
.
This is similar to the truth value of part (a).
Since in both satisfied and
for both the points.
c)
if that is
and
Here this satisfies the condition
.
Then
This also satisfies the condition
.
Hence exists and it is true.
d)
Assume
Here satisfies the condition
Then
satisfies the condition
.
Thus, point exists and it is true. This satisfies the same values as in part (c)
