Question

помогите плиз
буду благодарен)

Answer 1

1.
а)
$sqrt{16} times sqrt{121} = 4 times 11 = 44$
б)
$sqrt{225} times sqrt{169} = 15 times 13 = 195$
2.
а)
$sqrt{0.25} + sqrt{36} = 0.5 + 6 = 6.5$
б)
$sqrt{8 - 2 times ( - 4)} = sqrt{8 + 8} = sqrt{16} = 4$
$sqrt{8 - 2 times 2} = sqrt{8 - 4} = sqrt{4} = 2$
$sqrt{8 - 2 times 3.5} = sqrt{8 - 7} = sqrt{1} = 1$
