Claro, vamos a resolver cada una de las expresiones en la forma [tex]\( a + bi \)[/tex] paso a paso. Recuerda que [tex]\(\sqrt{-1} = i\)[/tex].
a. [tex]\(\sqrt{-16}\)[/tex]
[tex]\[ \sqrt{-16} = 4i \][/tex]
Por lo tanto, en forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 4i = 4i \)[/tex].
b. [tex]\(-\sqrt{-100}\)[/tex]
[tex]\[ -\sqrt{-100} = -10i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 - 10i = -10i \)[/tex].
c. [tex]\(\sqrt{-200}\)[/tex]
[tex]\[ \sqrt{-200} = \sqrt{200} \cdot i = 10\sqrt{2} \cdot i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 14.142135623730951i \)[/tex].
d. [tex]\(\sqrt{-75}\)[/tex]
[tex]\[ \sqrt{-75} = \sqrt{75} \cdot i = 5\sqrt{3} \cdot i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 8.660254037844386i \)[/tex].
e. [tex]\(i \sqrt{-1}\)[/tex]
[tex]\[ i \sqrt{-1} = i \cdot i = i^2 = -1 \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\(-1 + 0i\)[/tex].
f. [tex]\(-\sqrt{-1}\)[/tex]
[tex]\[ -\sqrt{-1} = -i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 - 1i = -1i \)[/tex].
g. [tex]\((\sqrt{-1})^2\)[/tex]
[tex]\[ (\sqrt{-1})^2 = i^2 = -1 \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\(-1 + 0i\)[/tex].
h. [tex]\(\sqrt{(-1)}\)[/tex]
[tex]\[ \sqrt{-1} = i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 1i = 1i \)[/tex].
i. [tex]\(\frac{\sqrt{-12}}{2}\)[/tex]
[tex]\[ \frac{\sqrt{-12}}{2} = \frac{2i\sqrt{3}}{2} = i\sqrt{3} \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 1.7320508075688772i \)[/tex].
j. [tex]\(\frac{\sqrt{-12}}{\sqrt{3}}\)[/tex]
[tex]\[ \frac{\sqrt{-12}}{\sqrt{3}} = \frac{2i\sqrt{3}}{\sqrt{3}} = 2i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 + 2i = 2i \)[/tex].
k. [tex]\(i^4\)[/tex]
[tex]\[ i^4 = (i^2)^2 = (-1)^2 = 1 \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 1 + 0i \)[/tex].
l. [tex]\(i^3\)[/tex]
[tex]\[ i^3 = i^2 \cdot i = -i \][/tex]
En forma [tex]\( a + bi \)[/tex] es [tex]\( 0 - 1i = -1i \)[/tex].
Estos son los resultados para cada una de las expresiones en la forma [tex]\( a + bi \)[/tex].
