Question

Find the multiplicative inverse of

11. 4 – 3i

Answer 1

$4 - 3i \\ inverse \: = (4 - 3i) \\ \\ > \frac{1}{4 - 3i} \\ on \: \: rationalizing = \frac{4 + 3i}{16 + 6} \\ = \frac{4 + 3i}{25}$

Answer 2

$\large{ \mathfrak{ \blue{question : - }}}$

$\huge{ \color{pink}{ \textbf{ \textsf{find \: the \: multiplicative \: inverse \: of}}}}$

$\huge{ \color{purple}{ \textbf{ \textsf{4 - 3i}}}}$

$\huge{ \mathfrak{ \red{answer : - }}}$

$\small{ \blue{4 - 3i}}$

$\small{ \pink{inverse = (4 - 3i)}}$

$\small{ \purple{ > \frac{1}{4 - 3i}}}$

$\small{ \red{on \: rationalizing \: = \frac{4 + 3i}{16 + 6} }}$

$\small{ \green{ = \frac{4 + 3i}{25}}}$
