A = 49 x 4 + 28 : 4 - 37
= 196 + 7 - 37
= 203 - 37

A=49 x 4 + 28 : 4 - 37
A=196 + 7 - 37
A=203 - 37
A=166
B= \(\frac{5}{2}\)+ \(\frac{1}{2}\)
B=\(\frac{6}{2}\)=3
A = 49 x 4 + 28 : 4 - 37
= 196 + 7 - 37 = 203 - 37 = 166.
B = 5/2 + 1/2 = 6/2 = 3
Tính :
A = 49 x 4 + 28 : 4 - 37
A = 196 + 7 - 37
A = 203 - 37
A = 166
B = \(\frac{5}{2}+\frac{1}{2}\)
B = \(\frac{6}{2}\)
B = \(3\)
Chúc bạn học tốt !
