Giải thích các bước giải:

a)(2019−8546)−(2020−8545)

=2019+8546 − 2020−8545

= 10565 - 10565

= 0

b)−47.(85−84)−84.(47−58)

= −47.1−84.(−11)

= −47+924

= 877

c)−167−297−(−297)+(−4)²+171−(−2)²

= −167−297−(−297)+16+171−4

= −167+0+16+171−4

= 16

d)(−6)².37−36.(−37)+37

= 36.37+36.37+37

= 37.(36+36+1)

= 37.73

= 2701

e)−25.72+25.(−28)+1500

= −25.72−25.28+1500

= −25.(72+28)+1500

= −25.100+1500

= −2500+1500

= −1000

f, (−2020)0.|−5|.16.(−3)²

= 1.5.16.9

= 80.9

= 720
