Answer:
Option 2 - P=1/ square root of 4 and W=1/square root of 9
Step-by-step explanation:
To find : For Which Value of P and W is P+W a rational number ?
Solution :
Solving each expression,
1) P= 1/ square root of 3 and W=1/square root of 6
i.e. and
It is an irrational number.
2) P=1/ square root of 4 and W=1/square root of 9
i.e. and
It is a rational number as repeating decimal.
3) P=1/square root of 6 and W=1/square root of 10
i.e. and
It is an irrational number.
4) P=1/square root of 25 and W=1/square root of 2
i.e. and
It is an irrational number.
Therefore, Option 2 is correct.
