Question

Find value of i9+1/i19​

Answer 1

Answer:

Here is your answer.....

Answer 2

Answer:

$\frac{170i}{19}$

Step-by-step explanation:

we have to find 9i+$\frac{1}{19i}$

as we know from complex numbers that i=imaginary number i.e=$\sqrt{-1}$

Therefore $i^{2}$=i×i=-1

now calculating the given question we get

multiplying numerator and denominator with i

$9i+\frac{1}{19i}=9i+\frac{1\times i}{19i\times i}$

$9i+\frac{i}{-19}$

$9i-\frac{i}{19}$

Taking L.C.M we get

$\frac{171i-i}{19}$

$\frac{170i}{19}$
