Question

give the answer of this question in detail

Answer 1

$Given : \sqrt{13 - x \sqrt{10} } = \sqrt{8} + \sqrt{5}$

$\sqrt{13 - x \sqrt{10} } = 2 \sqrt{2} + \sqrt{5}$

On Squaring both sides, we get

$( \sqrt{13 - x \sqrt{10} } )^2 = (2 \sqrt{2} + \sqrt{5} )^2$

$13 - x \sqrt{10} = 4 \sqrt{10} + 13$

$-x \sqrt{10} = 4 \sqrt{10}$

x = -4.
