Tính giá trị biểu thức:
A=(a-b)(a2+ab+b2) với a=5;b=-6
(NHANH GIÚP MÌNH NHA,MÌNH CẦN GẤP LẮM,AI XONG TRƯỚC VÀ ĐÚNG ,MÌNH SẼ BÌNH CHỌN ĐÚNG CHO)
Ta có: \(A=\left(a-b\right).\left(a^2+a.b+b\right)^2\)
Hay \(A=\left[5-\left(-6\right)\right]\left[5^2+5.6+\left(-6\right)^2\right]\)
\(\Leftrightarrow A=11.\left[25+30+36\right]\)
\(\Leftrightarrow A=11.91\)
\(\Leftrightarrow A=1001\)
hok tốt!!
Thay a=5; b=-6 vào biểu thức A =(a-b)(a^2+ab+b^2) ta có:
A=[5.(-6)].[5^2+5.(-6)+(-6)^2]
=(-30).[25+(-30)+36]
= (-30) .(-5+36)
=(-30).31
=-930
Nhớ nha
Cho mình làm lại nha
Thay a=5; b=-6 vào biểu thức A=(a-b).(a^2+ab+b^2) ta có
A=[5-(-6)].[5^2+5.(-6)+(-6)^2]
=11.[25+(-30)+36]
=11.(-5+36)
=11.31
=341
Nhớ k cho tớ nhé
