Question

caucule a expressao algebrica m2+6mn+n2 para m=2/3 e n=1/2

Answer 1

Para $m= \frac{2}{3}$ e $n= \frac{1}{2}$

$m^{2}+6.m.n+n^{2}$
$( \frac{2}{3} )^{2}+6. \frac{2}{3} . \frac{1}{2}+( \frac{1}{2})^{2}$
$\frac{4}{9}+ \frac{12}{6}+ \frac{1}{4}$

mmc(9,6,4)=36

$\frac{4.4+6.12+9.1}{36}$

$\frac{16+72+9}{36} = \frac{97}{36}$

Espero ter ajudado, me atrapalhei um pouco com o editor de fórmulas :D
