147x147=21609

nha bạn                                                              ^_^

1+1=2

147*147=21609

Minhd đang cần gấp bạn nào chỉ mình với ạ

135 . (-12 + 147) - 147 . (135 - 12)

= 135 . (-12) + 135 . 147 - 147 . 135 - 147 . (-12)

= [(135 . 147) - (147 . 135)] + (-12) . (135 - 147)

= (-12) . (-12) = 144

\(135.\left(-12+147\right)-147.\left(135-12\right)\)

\(=135.\left(-12\right)+135.147-147.135-147.\left(-12\right)\)

\(=\left(135.147-147.135\right)+135.\left(-12\right)-147.\left(-12\right)\)

\(=0-12.\left(135-147\right)\)

\(=-12.\left(-12\right)\)

\(=144\)
