Answer 2

thanks for this great question,

dear mate;

HOPE this HELPS...

Answer:

6

Step-by-step explanation:

dear mate we can use the following identity in this question:

(a+b)(a-b)=(a)sq.-(b)sq.

dear mate,

let a be 3 and b be root3 respectively.

then the solution will be as follows....

(3+root3)(3-root3)

=3(sq.)-root3(sq.)

=9-3=6

Additional information:

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

These are few identities which can be helpful ....
