Answer 1

Explicación paso a paso:

A)

-3(2+3i)+2(-1-4i)-(2-5i)

-6-9i-2-8i-2+5i

-10-12i........rpta

B)

[(2+3i)-(-1-4i)]·(2-5i)

[3+7i](2-5i)

6-15i+14i-35(-1)

41-i......rpta

C)

(2+3i)/(2-5i)

racionalizamos...

[(2+3i)(2+5i)]/[(2-5i)(2+5i) ]

[4+10i+6i+15(-1)]/[4-25(-1)]

(-11+16i)/(29)......rpta
