Question

(Route 3 +route 5) square

Answer 1

(√3+√5)²

according to the algebraic identity (a+b)²...we can also solve(√3+√5)²

so,....

(√3+√5)²

=> (√3)² + (√5)²+ 2×√3×√5

=> 3+5+ 2√15

=> 8+2√15

hence your answer is 8+2√15

Answer 2

Answer:

Step-by-step explanation:

Here, root 5 = a, root 3 = b

Question is in the form of,  (a+b)^2= a^2 + b^2 + 2ab

= (root 3)^2 + (root 5)^2 + 2 (root 3) (root 5)

= 3 + 5 + 2 root 15

= 8 + 2 root 15

Hope it helps :)
