Answer 1

hey mate answer is in the following attachement mark as brainlist please if the answer satisifies u and follow me buddy

Answer 2

$\huge\sf{ \underline{Question}}$

• $\sf{Simplify (1+\sqrt{2})(3-2\sqrt{2})}$

$\huge\sf{ \underline{Answer}}$

• $\sf{\sqrt{2}-1}$

$\huge\sf{ \underline{Solution}}$

${}$

$\mapsto\sf{(1+\sqrt{2})(3-2\sqrt{2})}$

${}$

$\mapsto\sf{3-2\sqrt{2}+3\sqrt{2}-4}$

${}$

$\mapsto\sf{\sqrt{2}+3-4}$

${}$

$\mapsto\sf{\sqrt{2}-1}$

${}$
