Express complex number in the form a + ib. ​

Answer»

ANSWER: 0+i0

Step-by-step EXPLANATION:

We KNOW that,

in a+ib, a represents real PART while ib represents the imaginary part.

Also,

i^{2}=-1\\

So,

i^{9}+i^{19}  can be written as,

=i*i^{8} +i*i^{18}

=i*(i^{2})^{4} +i*(i^{2} )^{9}                              \left[ as,\\a^{mn} = (a^{m})^{n} ]

Putting i^{2}=-1,

=i*(-1)^{4}+i*(-1)^{9}

=i*1+i*(-1)

=i-i

=0

Therefore,

0+i0 is the REQUIRED answer.
