Ai nhanh nha^'t tk
222 + 222 = ?
123 + 123 = ?
555 × 2 = ?
Giúp mk lên 300 SP nha m.n
Mk sẽ đáp đền, những ai tk cho mk lên bao nhiu đ thỳ sau khi đc 300 SP sẽ đc tk lại bấy nhiu
Cho mk hỏi : tại sao khi có ng tk đúng cho mk, mk ko nhận đc thông báo từ OLM ?
111 + 222 = ?
ai nhanh mình tk cho
222 + 222=
ai tk minh minh tk lai cho
222+222+333+444+555+666=???????
Bn nào nhanh tay mk tick cho
so sanh 222 mu 333 va 333 mu 222
nhanh len nhe minh se co mot mk ai nhanh nhat se duoc
bạn chỉ cần so sánh phần bù là ok nhé kb vs mk nhé
222+222=
444+444=
Đổi tk ko ? Cần 6 tk nx thôi để đủ 1100SP
Trả lời :
222+222=444
444+444=888
\(\downarrow\)
Trả lời
222 + 222 = 444
444 + 444 = 888
Hok tốt
Ok 3-3
222 + 222 =444
444 + 444 =888

Áp dụng hằng đẳng thức sau
an−1=(a−1).[an−1+an−2+...+1]=(a−1).pan−1=(a−1).[an−1+an−2+...+1]=(a−1).p (nn là 1 số nguyên dương)
an+1=(a+1).[an−1−an−2+..+1]=(a+1).qan+1=(a+1).[an−1−an−2+..+1]=(a+1).q (nn là 1 số nguyên dương lẻ)
Thay vào ta được như sau:
+) 222333−1=(222−1).p=13.17.p222333−1=(222−1).p=13.17.p
+) 333222+1=(3332)111+1=110889111+1=(110889+1).q=13.8530.q333222+1=(3332)111+1=110889111+1=(110889+1).q=13.8530.q

a) \(222^{333}+333^{222}\)
\(=\left(111.2\right)^{333}+\left(111.3\right)^{222}\)
\(=111^{333}.2^{333}+111^{222}.3^{222}\)
\(=111^{222}.\left(111^{111}.2^{333}+3^{222}\right)\)
\(=111^{222}.\left(111^{111}.2^{3.111}+3^{2.111}\right)\)
\(=111^{222}.\left[111^{111}.\left(2^3\right)^{111}+\left(3^2\right)^{111}\right]\)
\(=111^{222}.\left(111^{111}.8^{111}+9^{111}\right)\)
\(=111^{222}.\left[\left(111.8\right)^{111}+9^{111}\right]\)
\(=111^{222}.\left(888^{111}+9^{111}\right)\)
\(=111^{222}.\left(888+9\right)\left[888^{110}-888^{109}.9+.....-888.9^{109}+9^{110}\right]\)
\(=111^{222}.7992\left[888^{110}-888^{109}.9+.....-888.9^{109}+9^{110}\right]\)
