化简 (tan^5(x))/(tan^3(x))

解答

化简

\frac{tan ^{5} ( x )}{tan ^{3} ( x )}

tan^{2} (x)

求解步骤

\frac{tan ^{5} ( x )}{tan ^{3} ( x )}

使用指数法则:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= tan^{5 - 3} (x)

数字相减:

5 - 3 = 2

= tan^{2} (x)

s im pl i f y (\frac{8}{( 27 a ^{3} )})^{\frac{- 2}{3}}

s im pl i f y \frac{f ( x ) x}{1 + x ^{2}}

s im pl i f y l^{- 1} [\frac{( 2 s - 6 )}{( s ^{3} - s )}]

e x p an d (3.92 - 2 x)^{2}

s im pl i f y (3 n^{2} - 2 x + 5 m) - (- 3 x + 5 m - 3 n^{2}) + n^{2} - x + m
