TINH GIA TRI BIEU THUC :A=1/30+1/42+1/56+1/72+1/90+1/110+1/132
tinh gia trị biểu thức :
A=\(\frac{1}{30}+\frac{1}{42}+\frac{1}{56}+\frac{1}{72}+\frac{1}{90}+\frac{1}{110}+\frac{1}{132}\)
1/30+1/42+1/56+1/72+1/90+1/110+1/132
A=-1/20+-1/30+-1/42+-1/56+-1/72+-1/90+-1/110+-1/132
A=1/30+1/42+1/56+1/72+1/90+1/110+1/132
A=1/30+1/42+1/56+1/72+1/90+1/110+1/132
B= 1/30 + 1/42 + 1/56 + 1/72 + 1/90 + 1/110 + 1/132
A = 1/30+1/42+1/56+1/72+1/90+1/110+1/132
