化简 (6xy^5)^3

解答

化简

(6 x y^{5})^{3}

216 x^{3} y^{15}

求解步骤

(6 x y^{5})^{3}

使用指数法则:

(a \cdot b)^{n} = a^{n} b^{n}

(6 x y^{5})^{3} = 6^{3} x^{3} (y^{5})^{3}

= 6^{3} x^{3} (y^{5})^{3}

6^{3} = 216

= 216 x^{3} (y^{5})^{3}

化简

(y^{5})^{3} : y^{15}

= 216 x^{3} y^{15}

f = 10 (70 - 65) + 50

s im pl i f y lo g_{7} (\frac{1}{4})

- \frac{1}{2} y + 5 = - \frac{1}{3} y + 4

3 x^{2} + 12 x = - 6

4 \geq 6 x - 12 - 8
