Question

Solve using identity (√11-√8)2

Answer 1

Answer:√3×2

Step-by-step explanation:[√11-√8]2

√3×2

2√3

Answer 2

$(\sqrt{11} - \sqrt{8})^{2} \\(a - b)^{2} = a^{2} - 2ab + b^{2} \\\sqrt{11}^{2} - 2 \sqrt{11} \sqrt{8} + \sqrt{8}^{2}\\11 - 2 \sqrt{88} + 8\\19 - 2 \sqrt{2X2X2X11}\\19 - 2X2 \sqrt{2X11}\\\\19 - 4 \sqrt{22}\\\\19 - 4X4.690\\19 - 19.84\\0.84$ Value of √22 = 4.690
