Giúp mình với ạ mình đang cần gấp giúp mình với ạ

a, 278.60+39.278+278.1^2023

= 278.(60+39+1)

=278.100

=27800

b, 8^2.29+4^3.71-500

=64.29+64.71-500

=64.(29+71)-500

=64.100-500

=6400-500

=63500

c, 32.25.125.21

=4.8.5.5.25.5.3.7

=2.2.8.5.5.5.5.5.3.7

=(2.5).(2.5).(8.5).(5.5).(3.7)

=10.10.(40.25).21

=100.1000.21

=100000.21

=2100000

d,37.49+63.124-52.63+37.23

=37.(49+23)+63.(124-52)

=37.72.63.72

=72.(37+63)

=72.100

=7200

e, 10^2:[(37-32)^3-5^10:5^8]+2023^0

=100:[5^3-5^10-8]+1

=100:[125-5^2]+1

=100:[125-25]+1

=100:100+1

=1+1=2

f,500-{5[409-(2^3.3-21)^2]+10^3}:15

=500-{5[409-(8.3-21)^2]+1000}:15

=500-{5[409-(24-21)^2]+1000}:15

=500-{5[409-3^2]+1000}:15

=500-{5[409-9]+1000}:15

=500-{5 400+1000}:15

=500-{2000+1000}:15

=500-300:15

=500-200

=300

g, tự làm nhé
