化简-x^2*x^2

解答

化简

- x^{2} \cdot x^{2}

- x^{4}

求解步骤

- x^{2} x^{2}

使用指数法则:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x^{2} = x^{2 + 2}

= - x^{2 + 2}

数字相加:

2 + 2 = 4

= - x^{4}

\frac{19 x}{20} - \frac{x - 1}{10} = x

\frac{4}{5} x - \frac{1}{8} \leq \frac{7}{10} x - \frac{8}{5}

s im pl i f y \frac{\frac{12}{13}}{\frac{- 5}{13}}

lo g_{\frac{3}{5}} (30) = 40

f a c t or 10 d^{2} + 17 d - 20
