Question

mn+14mn-81mn-mn+20mn​

Answer 1

Respuesta:

$mn - 68mn + 20mn$

$47mn$=0

$nm = \frac{1}{47}$

$m = \frac{1}{47} \div n$

$m = \frac{n}{47}$

$n \times ( \frac{n}{47}) = \frac{1}{47}$

${n}^{2} \div 47 = \frac{1}{47}$

${n}^{2} = \frac{ \frac{1}{47} }{47} = \frac{1}{2209}$

$n = \sqrt{ \frac{1}{2209} }$

$n = \frac{1}{47}$

$m = \frac{ \frac{ \frac{1}{47} }{1} }{47}$

$m = 1$
