tick mình nha Đinh Minh Phong!

5800 nhé bạn
Ht

=58x{75+50-25}=58x100=5800

\(58.75+58.50+58.25=58.\left(75+50+25\right)=58.150=8700\)

= 58. ( 75+50+25)

= 58. 150 = 8700

đúng ko

58.75-58.50-58.25=58(75-50-25)=58.0=0

58.75 - 58.50 - 58.25=58.(75-50-25)=58.0=0

58.75+58.50-58.25

=58.(75+50-25)

=58.100

=5800

Tích mình nhé!

20:2^2 -5^9:5^8

58.75+58.50-58.25

=> 58.(75+50-25)

=> 58.(125-25)

=> 58.100

=> 5800

58.75+58.50-58.25

=58.(75+50-25)

=58.100

=5800

58.75+58.50-58.25

=58.(75+50-25)

=58.100

=5800

chúc bạn học tốt !!!

58.75 + 58.50 - 58.25

Cảm ơn các bạn nhiều
