Question

6. If m = 4 and n = -2, then find the value of
( n/m + m/n ) -n

Useless answer, I will report


Only correct answer.

Answer 1

Answer:

$= ( \frac{n}{m} + \frac{m}{n} ) - n$

$= (\frac{ - 2}{4} - \frac{4}{2} ) + 2$

$= ( \frac{ - 2}{4} - \frac{4 \times 2}{2 \times 2} ) + 2$

$= ( \frac{ - 2}{4 } - \frac{8}{4} ) + 2$

$= ( \frac{ - 10}{4} ) + 2$

$= \frac{ - 5}{2} + 2$

$= \frac{ - 5 + 4}{2}$

$= \frac{ - 1}{2}$

$\huge\mathcal\red{I}$   $\huge\mathcal\red{will}$   $\huge\mathcal\red{return}$   $\huge\mathcal\red{you}$   $\huge\mathcal\red{back.}$

Answer 2

Answer:

(n/m + m/n) - n --> (1)

Putting m = 4 , n = -2 in (1)

(-2/4 + 4/-2) -(-2)

= (-1/2 - 2) + 2

= (-1-4/2) + 2

= -5/2 +2

= (-5+4)/2

= -1/2
