a.(2xy +7yz) (2xy +7yz)

Answer 1

Answer:

2xy×7yz×9xz=(2×7×9)×xy×yx×xz

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x 2

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x 2 y

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x 2 y 2

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x 2 y 2 z

2xy×7yz×9xz=(2×7×9)×xy×yx×xz =126x 2 y 2 z 2
