Question

Thực hiện phép tính sau:

1500 - {5³. 2³ - 11.[7² - 5.2³ + 8.(11² - 121)]} 

Please help meeeeee

Answer 1

1500-{5³.2³-11.[7²-5.2³+9.(11²-121)]}

=1500-{125.8-11.[49-5.8+8.(121-121)]}

=1500-{125.8-11.[49-8.(5+0)]}

=1500-{125.8-11.[49-8.5]}

=1500-{125.8-11.[49-40]}

=1500-{125.8-11.9}

=1500-{1000-99}

=1500-901

=699

Answer 2

1500 - {5³. 2³ - 11.[7² - 5.2³ + 8.(11² - 121)]} 

= 1500 - {125 . 8 - 11 . [49 - 5 . 8 + 8 . (121 - 121)]}

= 1500 - {1000 - 11 . [49 - 40 + 8 . 0]}

= 1500 - {1000 - 11 . [49 - 40 + 0]}

= 1500 - {1000 - 11 . 9}

= 1500 - (1000 - 99)

= 1500 - 901

= 599
