Đáp án:
Giải thích các bước giải:
H = ( 1 + 3 + 5 + …… + 99 ) . ( 36 . 333 – 108 . 111 )
H = ( 1 + 3 + 5 + …… + 99 ) . ( 36.3.111 – 108.111)
H = ( 1 + 3 + 5 + …… + 99 ) . (108.111 – 108.111)
H = ( 1 + 3 + 5 + …… + 99 ) . 0
H = 0
M =20202021 . 2020 – 20202020 . 2021
M = 20202021.2020 – 20202020.2020 + 20202020
M = 2020.(20202021 – 20202020) + 20202020
M = 2020.1 + 20202020
M = 2020.1 + 2020.10001
M = 2020 ( 1 + 10001)
M = 2020.10002
M = 20204040
