\frac{( a ^{n + 3} )}{a ^{n - 5}}

a^{8}

求解步骤

\frac{a ^{n + 3}}{a ^{n - 5}}

使用指数法则:

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

\frac{a ^{n + 3}}{a ^{n - 5}} = a^{n + 3 - (n - 5)}

= a^{n + 3 - (n - 5)}

e x p an d \frac{( s ( s + 2 ) )}{( s ^{2} + 4 )}

e x p an d \frac{a + 4}{( a + 1 ) a}

e x p an d (- 2 + i) (i + 1) ((- 2 + i)^{2} + 4 (- 2 + i) + 8)

e x p an d \frac{( 59 e ^{6} 10 e ^{9} ) - 29}{69}

e x p an d \frac{4 27}{4 3}
