tính
a=(1+(7/9))x(1+(7/20))x(1+(7/33))x...........x(1+(1/2900))
1-tính tích
p=(1+7/9)(1+7/20)(1+7/33)...(1+7/2900)
Tính nhanh :
A = ( 1 + 7/9 ).(1+7/20).(1+7/33 )....( 1 + 7/2900 )
Tính P=(1+7/9).(1+7/20).(1+7/33)...(1+7/2900)
Tính và so sánh:
a. A= ( 1+7/9)(1+7/20)(1+7/33).............(1+7/2900) với 7
1/ Tìm giá trị nhỏ nhất của biểu thức: A= |x-20| + |y+5| - 2015
2/ Tính: \(B=\left(1+\frac{7}{9}\right)\left(1+\frac{7}{20}\right)\left(1+\frac{7}{33}\right)....\left(1+\frac{7}{2900}\right)\)
tính tích P=[1+\(\frac{7}{9}\)].[1+\(\frac{7}{20}\)].[1+\(\frac{7}{33}\)]...[1+\(\frac{7}{2900}\)]
Tính tổng dãy sau: (1+7/9)x(1+7/20)x(1+7/33)x.......x(1+7/153)x(1+7/180)
