Question

State whether the number (√2-√3)(√2+√3) is rational or irrational. Justify

Answer 1

Answer:

$answer \: 1$

Answer 2

Answer:

rational number.

Step-by-step explanation:

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

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

=2-3=-1

-1 is rational number hence,

(root 2-root 3)(root 2 + root 3) is also rational number.
