Question

Решите, с меня 15 б вот

Answer 1

$3 sqrt{ frac{36}{25} } - 1 = 3 times frac{6}{5} - 1 = frac{18}{5} - 1 = frac{13}{5} = 2 times frac{3}{5}$

$sqrt{0.75} times sqrt{0.3} = sqrt{0.75 times 0.3} = sqrt{0.225} = 15 sqrt{0.001}$

$frac{ sqrt{250} }{ sqrt{10} } = sqrt{ frac{250}{10} } = sqrt{25} = 5$

$sqrt{ {5}^{4} times {2}^{6} } = {5}^{2} times {2}^{3} = 25 times 8 = 200$

задание 2.

$2 sqrt{128} - sqrt{72} = 2 sqrt{64 times 2} - sqrt{9 times 4 times 2} = 2 times 8 sqrt{2} - 3 times 2 sqrt{2} = 16 sqrt{2} - 6 sqrt{2} = 10 sqrt{2}$

$(3 sqrt{2} + sqrt{50} ) sqrt{2} = (3 sqrt{2} + 5 sqrt{2} ) sqrt{2} = 8 sqrt{2} times sqrt{2} = 16$

${(6 - sqrt{3} )}^{2} = 36 - 12 sqrt{3} + 9 = 45 - 12 sqrt{3} = 3(15 - 4 sqrt{3} )$

задание 3.

$12 sqrt{3} = sqrt{144 times 3} = sqrt{432} \ - 8 sqrt{5} = sqrt{64 times 5} = sqrt{320}$

$sqrt{ {a}^{2} - 12a + 36 } = sqrt{ {(a - 6)}^{2} } = a - 6 \ a = 5.9 = > a - 6 = 5.9 - 6 = - 0.1$
