Question

if p equal to root 3 minus root 2 divided root 3 + root 2 and q equal to root 3 + root 2 divided root 3 minus root 2 find p square + q square

Answer 1

Answer:

We know that,

(p + q)² = p² + q² + 2pq

=> (p + q)² - 2pq = p² + q²

=> p² + q² = (p + q)² - 2pq .....(1)

First we calculate

Now,

We calculate

Putting value of (p+q)² and pq in (1)

We get,

p² + q² = 100-2×1 = 100-2 = 98

=> p² + q² = 98

Answer 2

Answer:

Step-by-step explanation:

P=√3-√2 /√3+√2

= √1/√5

q=√3+√2 /√3-√2

=√5 /√1

According to question, ( ^ means square)

P^+q^ = 1/5+5/1

=26/5. Ans.
