Question

(√5−√7)(√5−√8) Multiply and Simplify?

Answer 1

$\sqrt{5} ( \sqrt{5} - \sqrt{8} ) - \sqrt{7} ( \sqrt{5} - \sqrt{8} )$

$5 - \sqrt{40} - \sqrt{35} - \sqrt{56}$

$5 - \sqrt{2 \times 2 \times 2 \times 5} - \sqrt{35} - \sqrt{2 \times 2 \times \times}$

$- \sqrt{2 \times 2 \times 2 \times 7}$

$5 - 2 \sqrt{10} - \sqrt{35 } - 2 \sqrt{14}$
