Question

I need help with this, write using a+bi equation form

6/9-7i

Answer 1

Do you mean 6/(9-7i)?

Answer 2

multiply it by its conjugate and it should all work out

Answer 3

\[\frac{6}{9-7i} =\frac{6}{9-7i} \times\frac{9+7i}{9+7i} \]
\[ =\frac{6(9+7i)}{(9-7i)(9+7i)}\]
\[ =\frac{54+42i}{81+49}\]
\[ =\frac{54+42i}{130}\]
\[ =\frac{27}{65}+\frac{21}{65}i\]
