Evaluate: xz (x^2 + y^2) for x = 2, y = 1 and z = 1.

xz (x 2 \+ y 2 ) = x (2+1) z \+ xzy 2 = x 3 z \+ xzy 2 For x = 2, y = 1 and z = 1 2 3 x 1 \+ 2 x 1 x 1 2 = 8 x 1 \+ 2 x 1 x 1 = 8 \+ 2 = 10 Hence, for x = 2, y = 1 and z = 1, the value of xz (x 2 \+ y 2 ) is 10.

Answer

xz (x² + y²)

= x⁽²⁺¹⁾z + xzy²

= x³z + xzy²

For x = 2, y = 1 and z = 1

2³ x 1 + 2 x 1 x 1²

= 8 x 1 + 2 x 1 x 1

= 8 + 2

= 10

Hence, for x = 2, y = 1 and z = 1, the value of xz (x² + y²) is 10.
