Answer 1

при а=-3

$3 \times \sqrt{10 - 2 \times ( - 3)} = 3 \times \sqrt{10 + 6} = 3 \times \sqrt{16} = 3 \times 4 = 12$

при а=3

$3 \times \sqrt{10 - 2 \times 3} = 3 \times \sqrt{10 - 6} = 3 \times \sqrt{4} = 3 \times 2 = 6$

при а=5

$3 \times \sqrt{10 - 2 \times 5} = 3 \times \sqrt{10 - 10} = 3 \times \sqrt{1} = 3 + 1 = 4$
