Question

root 5 + root 3 * root 5 + root 3

Answer 1

Answer:

Step-by-step explanation:

(√5+√3)(√5+√3)

= (√5+√3)²

EXPANDING BASED ON THE IDENTITY

(A+B)² = A²+B²+2AB

= (√5)²+(√3)²+2*(√5)(√3)                  

NOTE :

√A*√A = A

√A*√B =√(AB)

= 5+3+2√10

= 8+2√10

= 2(4+√10)

HOPE THIS HELPS.
