Question

thực hiện phép tính

a:222+967+178-267+209

b:8.25.29.2mux2.125

 

Answer 1

222+ 967 +178 -267 +209

= (222 + 178) + (967 - 267) +209

= 400+700+209

= 1309 

 

8.25.29. 2^2.125

= 8. 25. 29. 4. 125

=(25.4) . (8. 125) .29

=100. 1000. 29

= 2900000

Answer 2

\(\text{222+967+178-267+209}=1309 \)
\(\text{8.25.29.2^2.125=2^3}.5^2.29.2^2.5^3=2^5.5^5.29=10^5.29=2900000\)

Answer 3

222+ 967 +178 -267 +209

= (222 + 178) + (967 - 267) +209

= 400+700+209

= 1309

 

8.25.29. 2^2.125

= 8. 25. 29. 4. 125

=(25.4) . (8. 125) .29

=100. 1000. 29

= 2900000

Answer 4

b: =800x125x29

=100000x29

=2900000
