25 \cdot 5^{2 k}

5^{2 + 2 k}

求解步骤

25 \cdot 5^{2 k}

分解整数

25 = 5^{2}

= 5^{2} \cdot 5^{2 k}

使用指数法则:

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

5^{2} \cdot 5^{2 k} = 5^{2 + 2 k}

= 5^{2 + 2 k}

e x p an d \frac{d ^{2}}{d x ^{2}} (4 x (x^{2} + 9) \cdot (x - 9)) + (x^{2} + 9)^{2}

e x p an d \frac{( x ^{2} - 5 ) ( x - 4 )}{( x + 1 ) ( 2 x ^{2} - 5 )}

e x p an d (sin (x) + cos (x)) e^{x}

e x p an d (2 e^{4 t} - 4 e^{- 3 t})^{2}

e x p an d ln (\frac{x ^{8}}{( x - 3 ) ^{4}})
