I₁/I₂ = 2

I_max/I_min = [( $\sqrt{I_{1}^{}}$ + $\sqrt{I_{2}^{}}$ )/( $\sqrt{I_{1}^{}}$ – $\sqrt{I_{2}^{}}$ )]² = [( $\sqrt{I_{2}/I_{1}}$ +1)/( $\sqrt{I_{2}/I_{1}}$ – 1 )]²

= [(2+1)/(2-1)]² = 9.

Hope it clears.If you like answer then please approve it.

I1/I2 = 2Imax/Imin = [(\sqrt{I_{1}^{}} +\sqrt{I_{2}^{}})/(\sqrt{I_{1}^{}} – \sqrt{I_{2}^{}})]2 = [(\sqrt{I_{2}/I_{1}} +1)/(\sqrt{I_{2}/I_{1}} – 1 )]2 = [(√2+1)/(√2-1)]2 = (3+2√2)/(3-2√2).
