5 raruraru e ōrite ana ki:
\frac { 18 \cdot ( - 3 ) ^ { 2 } } { ( - 3 ) ^ { 4 } + 81 }
Tohaina
Kua tāruatia ki te papatopenga
\frac{18\times 9}{\left(-3\right)^{4}+81}
Tātaihia te -3 mā te pū o 2, kia riro ko 9.
\frac{162}{\left(-3\right)^{4}+81}
Whakareatia te 18 ki te 9, ka 162.
\frac{162}{81+81}
Tātaihia te -3 mā te pū o 4, kia riro ko 81.
\frac{162}{162}
Tāpirihia te 81 ki te 81, ka 162.
1
Whakawehea te 162 ki te 162, kia riro ko 1.
