化简 ((x^2+1)/(x^2-1))^3

解答

化简

(\frac{x ^{2} + 1}{x ^{2} - 1})^{3}

\frac{( x ^{2} + 1 ) ^{3}}{( x ^{2} - 1 ) ^{3}}

求解步骤

(\frac{x ^{2} + 1}{x ^{2} - 1})^{3}

使用指数法则:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{( x ^{2} + 1 ) ^{3}}{( x ^{2} - 1 ) ^{3}}

h \to 0 lim (3 h + 6)

x \to 0 lim (\frac{cos ( 4 x ^{2} )}{x})

\int \frac{5}{3 - 4 x - x ^{2}} d x

t a y l or x ln (x), 1

x \to 0 lim (arctan (x^{2} + 1))
