Tohaina
Kua tāruatia ki te papatopenga
1+2\sqrt{3}-\left(-\frac{1}{3}\right)^{-1}
Tīkina te uara \tan(60) mai i te ripanga uara pākoki.
1+2\sqrt{3}-\left(-3\right)
Tātaihia te -\frac{1}{3} mā te pū o -1, kia riro ko -3.
1+2\sqrt{3}+3
Ko te tauaro o -3 ko 3.
4+2\sqrt{3}
Tāpirihia te 1 ki te 3, ka 4.
