The given question is not an equation,  it is  an expression with irrational numbers..  a surd or radical expression.

It is the rationalization of irrational numbers.

\frac{1}{\sqrt3+\sqrt2}=\frac{1}{\sqrt3+\sqrt2}*\frac{\sqrt3-\sqrt2}{\sqrt3-\sqrt2}\\\\=\frac{\sqrt3-\sqrt2}{(\sqrt3)^2-(\sqrt2)^2}=\frac{\sqrt3-\sqrt2}{3-2}=\sqrt3-\sqrt2

1/√3+√2
on rationalize
1            × √3-√2
√3+√2      √3-√2
√3-√2   ⇒√3-√2
3-2
on using (a-b)(a+b)=a²-b²
