Tohaina
Kua tāruatia ki te papatopenga
z=-\frac{4}{9}\left(-\frac{3}{2}\right)
Me whakarea ngā taha e rua ki te -\frac{3}{2}, te tau utu o -\frac{2}{3}.
z=\frac{-4\left(-3\right)}{9\times 2}
Me whakarea te -\frac{4}{9} ki te -\frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
z=\frac{12}{18}
Mahia ngā whakarea i roto i te hautanga \frac{-4\left(-3\right)}{9\times 2}.
z=\frac{2}{3}
Whakahekea te hautanga \frac{12}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.
