Thu gọn rồi tính : c = x ( x^2 +6x) +4 ( 3x+2) với x=-11 e = ( y^3 +x^2 y ) (x^2 +y^2) - y (x^4+y^4 ) với x = 1,5 ; y= -2
f = 6xy( xy- y^2) -- 8x ( x-y^2 ) + 5y^2 ( x^2 - xy ) với x= 1/2 , y = 2

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
