expand (1.6-j^{1.2})^2

expand

(1.6 - j^{1.2})^{2}

2.56 - 3.2 j^{1.2} + j^{2.4}

Solution steps

(1.6 - j^{1.2})^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(1.6 - j^{1.2})^{2} = 1. 6^{2} - 2 \cdot 1.6 j^{1.2} + (j^{1.2})^{2}

= 1. 6^{2} - 2 \cdot 1.6 j^{1.2} + (j^{1.2})^{2}

Simplify

1. 6^{2} - 2 \cdot 1.6 j^{1.2} + (j^{1.2})^{2} : 2.56 - 3.2 j^{1.2} + j^{2.4}

= 2.56 - 3.2 j^{1.2} + j^{2.4}

2^{\frac{1}{2}} n (n - 1)^{2}

(x + 12)^{3}

\frac{( 1 + 2 ^{b} )}{( 1 + 2 ^{- b} )}

x^{3} + 5 x^{2} + 3 x + 1 x - 1

(3 a + 4 b)^{8}
