Step-by-step explanation:
i) (3+√3)(2+√2)
⇒3(2+√2) + √3(2+√2)
⇒3 × 2+ 3 ×√2+ √3 × 2+ √3+√2
⇒6 + 3√2 + 2√3 +
⇒ 6 + 3√2 + 2√3 + √6
ii) (3+√3)(2+√2 )
This is the same as the first one!
iii) (√5+√2)
2.2360679775 + 1.41421356237 = 3.65028153987
(iv) (√5-√2)(√5+√2)
we know that, (a+b) (a-b)= a²-b²
Putting a= √5, b= √2
⇒(√5)²-(√2)²
⇒5-2
⇒3
Hope it helps, please mark me as brainliest, thanks! :)
