\

The equation is $\"\"$

\

To find the value of n and m set the real parts equal to each other and the imaginary

\

parts equal to each other. $\"\"$

\

Real parts:

\

$\"\"$

\

According to subtraction property of equality: if $\"\"$ then $\"\"$ .

\

$\"\"$ (Subtract 4 from each side)

\

$\"\"$ (Commutative proprty: $\"\"$ )

\

$\"\"$ (Additive inverse property: $\"\"$ )

\

$\"\"$ (Additive identity property: $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ ) $\"\"$

\

Imaginary parts:

\

$\"\"$

\

According to Addition property of equality: if $\"\"$ then $\"\"$ .

\

$\"\"$ (Add 7 to each side)

\

$\"\"$ (Additive inverse property: $\"\"$ )

\

$\"\"$ (Additive identity property: $\"\"$ )

\

$\"\"$ (Add: $\"\"$ )

\

$\"\"$ (Divide each side by 3)

\

$\"\"$ (Cancel common terms) $\"\"$

\

The values of m and n are $\"\"$ and $\"\"$ respectively.
