Question

Calculați: √(√7-2)^2•√(√7-3)^2
Va rog,,

Answer 1

√(√7 - 2 )^2 • √(√7 - 3 )^2
(√7 - 2 ) • (√7 - 3)
7 - 3√7 - ( 2√7 - 6 )
7 - 3√7 - 2√7 + 6
13 - 5√7

Answer 2

$\sqrt{(\sqrt{7}-2) } ^{2} * \sqrt{(\sqrt{7}-3) } ^{2}=$

$=(\sqrt{7}-2)( \sqrt{7}-3) = 7 - 3\sqrt{7} - 2\sqrt{7} + 6 = 13 - 5\sqrt{7}$
