Answer 1

Здравствуйте!

$1) : 10 {}^{2} - 7 {}^{2} = 100 - 49 = 51 \ 2) : 5 {}^{3} - 5 {}^{2} = 125 - 25 = 100 \ 3) : 42 {}^{2} div 14 - 4 {}^{2} times 6 = \ = 1764 div 14 - 16 times 6 = \ = 126 - 96 = 30$
$4) : 8 {}^{3} div 4 {}^{2} - 2 {}^{3} = \ = 512 div 16 - 8 = \ = 32 - 8 = 24 \ 5) : 25 {}^{2} div (24 {}^{2} + 7 {}^{2} ) = \ = 625 div (576 + 49) = \ = 625 div 625 = 1$
$6) : 10 {}^{3} - 10 {}^{2} + 9 {}^{3} = \ = 1000 - 100 + 729 = \ = 1629$

Удачи в учёбе!!
