Answer 1

Answer:

(b)z²+2z+1

Step-by-step explanation:

{z+(4/3)⁰}²

=(z +1)²

=z²+2×1×z +1²

=z²+2z+1

Answer 2

Answer:

$\green{ \{ { \sf \: z + {( \frac{4}{3} })^{0} } \}^{2} = \sf {z}^{2} + 2z + 1}$

Step-by-step explanation:

$\sf \: { \{z + {( \frac{4}{3} })^{0} } \}^{2} \\ \\ { \huge{ \{}}\sf \: we \: know \: that \: anything \: to \: the \: \\ \sf \: power \: \: zero(0) = 1 \: \: \: \: that \: is \: mean \: \\ \sf \: {a}^{0} = 1 \: \: \pink{ where \: \: a \neq \: 0 } \\ \\ \sf \: so \: \: \: {( \frac{4}{3} })^{0 } = 1 \: \: \: \: \: \: \huge{ \}}\\ \\ = \sf{(z + 1)}^{2} \\ = \sf {z}^{2} + 2 \times z \times 1 + {1}^{2} \\ = \sf \: {z}^{2} + 2z + 1$
