Answer 2

Answer:

Step-by-step explanation:

(a + b )² = a² + b² + 2ab

so: (√3 + √7 )² =  (√3)² + (√7)² + 2 (√3 . √7)

= 3 + 7 + 2(√21)

10 + 2√21

this much is enough for exams but if you want the exact value , then take the square root value of √21. that i will done below

3 + 7 + 2(√21)

10 + 2√21

√21 = 4.58

10 + 2(4.58)

10 + 9.16

19.16
