Question

(a+b+2 root a root b) can be rewritten as |

Answer 1

Answer:

C)

$( \sqrt{a} \: + \: \sqrt{b} )^{2}$

Step-by-step explanation:

If A = root a

and B = root b

then we can use the identity

$(x + y) ^{2} = x ^{2} + {y}^{2} + 2xy$

Answer 2

Answer:

C.(√a+√b)²

Step-by-step explanation:

a+b+2√a√b [Using Identity:(x+y)²=x²+y²+2xy]

(√a+√b)²
