Question

(b)Find the product of 8xy, x2y, 2xy2​

Answer 1

Answer:

We have

(i) 3x + 7x = (3 + 7)x = 10x

(ii) -5xy + 9xy = ( -5 + 9)xy = 4xy

Answer 2

$\bf \: product \: = \: 8xy \times {x}^{2} y \times 2x {y}^{2} \\ \bf = 16 ({x}^{1 + 2 + 1} )( {y}^{1 + 1 + 2} ) \\ \bf \: = 16 {x}^{5} {y}^{5}$
