300

k mình nha rùi mk kb

100+200=300

100 + 200 = 300

100+200*35:7

=100+1000

=1100

bạn tk ....

100 + 200 x 5 = 100 + 1000 = 1100

100+200x5=100+1000=1100 nhé

200+100=?

tra loi

 200+100=300

\(200+100=300nha\)

200+100 =300

100+200=300nha

k mik đi mik đang âm điểm

=300 nha

300 nhé bạn tk cho mik

100+100=200

200+200=400

700+700=1400

100 + 100 = 200

200 + 200 = 400

400 + 400 = 800

700 + 700 = 1400

200

400

800

1400

Bằng 200

= 200 

tk mik nhé bạn 

100+100=200

100+100 *100=100+10000=10100

Nhớ k mik nha, thanks

=20000

= 100 + 10000

= 10100 nhé bạn

200+300+400+500

=500+400+500

=900+500

=1400

200+300+400+500=1400

200+300+400+500=1400

mik nhanh nhất nì ^_^

\(\frac{4}{3}B=-1+\frac{3}{4}-\left(\frac{3}{4}\right)^2+...+\left(\frac{3}{4}\right)^{99}\)

\(B=-\frac{3}{4}+\left(\frac{3}{4}\right)^2-\left(\frac{3}{4}\right)^3+...+\left(\frac{3}{4}\right)^{100}\)

\(\Rightarrow\)\(\frac{7}{3}B=-1+\left(\frac{3}{4}\right)^{100}\Rightarrow B=\frac{\left(\frac{3}{4}\right)^{100}-1}{\frac{7}{3}}=\frac{3\left[\left(\frac{3}{4}\right)^{100}-1\right]}{7}\)

Như vầy đủ gọn chưa bạn?
