展开 (20(5+3t))/(1+0.04t)

解答

展开

\frac{20 ( 5 + 3 t )}{1 + 0.04 t}

\frac{100 + 60 t}{1 + 0.04 t}

求解步骤

\frac{20 ( 5 + 3 t )}{1 + 0.04 t}

乘开

20 (5 + 3 t) : 100 + 60 t

= \frac{100 + 60 t}{1 + 0.04 t}

e x p an d \frac{( 2 a - 1 ) ( 4 a - 1 ) ^{2}}{32}

e x p an d \frac{sin ( ( n - 2 ) π )}{( n - 2 ) π}

e x p an d \frac{4 x + 1}{x ^{2} ( x ^{2} + x + 1 )}

e x p an d \frac{4}{( s + 4 ) ^{3}}

e x p an d (4 t + e^{t}) (4 - t)
