Question

solve n(-5)4÷n2=5.
$solve n( - 5)4 \ \div n = 5$
​

Answer 1

Find the value of n

$- 5 \times \frac{4}{ {n}^{2} } = 5$

$\frac{ - 20}{5} = {n}^{2}$

$-4= {n}^{2}$

2 or -2=n

n=2 or n=-2 if the question is $n( - 5) \times \frac{4}{ {n}^{2} } = 5$

$\frac{ - 20n}{ {n}^{2} } = 5$

$\frac{ - 20}{n} = 5$

$\frac{ - 20}{5} = n$

-4=n
