85 (√8-150)/2; 2) (12-175)√3; 3) (475-3-20) 15; 4)(718+(27) 3; 5) (175 - J12) 23; 6) (25 - (20) 15. (√75 - √12) √5. ​

Answer 1

Ответ:

$1) \sqrt{16} - \sqrt{100} = - 6 \\ 2) \sqrt{36} - \sqrt{225} = - 9 \\ 3)4 \sqrt{25 } - 3 \sqrt{100} = 20 - 30 = - 10 \\ 4)7 \sqrt{9} + \sqrt{81} = 21 + 9 = 30 \\ 5)2 \sqrt{225} - 2 \sqrt{36} = 30 - 12 = 18 \\ 6)2 \sqrt{25} - \sqrt{100} = 10 - 10 = 0$
