For which value of p and w is p+w a rational number. tell me how you got that answer
1) p= 1/ square root of 3 and w=1/square root of 6
2)p=1/ square root of 4 and w=1/square root of 9
3)p=1/square root of 6 and w=1/square root of 10
4)p=1/square root of 25 and w=1/square root of 2

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.
