Question

(3+rott 3)+(3-rott 3​

Answer 1

Answer:

6

Step-by-step explanation:

9-3

Use formula (a+b) (a-b) = a^2-b^2

Answer 2

Answer:

6

Step-by-step explanation:

dear mate, thanks for the question

I think it is (3+root3)(3-root3)

and if it's so, then,

let's go :)

dear mate in this we can use the identity

(a+b)(a-b)=a^2-b^2

Here, a =3 and b= root3

therefore,

(3+root3)(3-root3)

=3^2-root3^2

=9-3

=6

HOPE this HELPS...

addition information:

these kind of questions need few identities like...

• (a+b)^2=a^2+b^2+2ab
• (a-b)^2=a^2+b^2-2ab etc...

really hope that this HELPS...
