c.
Step-by-step explanation:
Rational number: The number which can be written as , where p and q are integers,
Irrational number: When the number Β is not rational number then, the number is called irrational number.
We have to find the irrational numbers.
a.
We can write as
Because
is a rational number because 1 and 2 are both integers and
Hence, a is not true.
b.
We know that is irrational number.
When a rational number is divided by irrational number then we get a irrational number.
is irrational number.
c.
We know that
is irrational number.Therefore,
is irrational number.
Hence, option c is true.
d.
1 is rational number.
Hence, option d is false.
e.
We know that is irrational number
Therefore, is irrational number.
Hence, option e is true.
