dấu chấm là dấu nhân nhé!!

Answer 1

Ta có: \(3^3.297-97.3^3+5^3\) = \(3^3\left(297-97\right)+5^3\) = \(27.200+125\) = \(5400+125\) = \(5525\)

\(2^3.2^2.5^2.5^3.7\) = \(2^5.5^5.7\) = \(\left(2.5\right)^5.7\) = \(10^5.7\) = \(100000.7\) = \(700000\)

\(2.12.5.5^2.6\) = \(24.5^3.6\) = \(144.5^3\) = \(144.125\) = \(18000\)

\(2^4.221+79.24\) = \(16.221+79.24\) = \(3536+1896\) = \(5432\)

\(234+432+118+216\) = \(234+216+432+118\) = \(450+550\) = \(1000\)

Chúc bạn học tốt!!!
