Whakaoti i te -x^{2}y-(-3x^2*7y)+16x^2y^3z/4y^2z=

$$- x ^ { 2 } y - ( - 3 x ^ { 2 } \cdot 7 y ) + \frac { 16 x ^ { 2 } y ^ { 3 } z } { 4 y ^ { 2 } z } =$$

Aromātai

$$24yx^{2}$$

Ngā Upane Otinga

Whakareatia te -3 ki te 7, ka -21.

$$\left(-x^{2}\right)y-\left(-21x^{2}y\right)+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

Ko te tauaro o -21x^{2}y ko 21x^{2}y.

$$\left(-x^{2}\right)y+21x^{2}y+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

Me whakakore tahi te 4zy^{2} i te taurunga me te tauraro.

$$\left(-x^{2}\right)y+21x^{2}y+4yx^{2}$$

Pahekotia te 21x^{2}y me 4yx^{2}, ka 25x^{2}y.

$$\left(-x^{2}\right)y+25x^{2}y$$

Pahekotia te -x^{2}y me 25x^{2}y, ka 24x^{2}y.

$$24x^{2}y$$

Kimi Pārōnaki e ai ki x

$$48xy$$
