受欢迎的代数 >

18000=10000(1+x)^{10}

解答

18000 = 10000 (1 + x)^{10}

解答

x = 10 \frac{9}{5} - 1, x = - 10 \frac{9}{5} - 1

+1

十进制

x = 0.06054 \dots, x = - 2.06054 \dots

求解步骤

18000 = 10000 (1 + x)^{10}

交换两边

10000 (1 + x)^{10} = 18000

两边除以

10000

(1 + x)^{10} = \frac{9}{5}

对于

(g (x))^{n} = f (a)

，n 为偶数，解为

g (x) = n f (a), - n f (a)

解

1 + x = 10 \frac{9}{5} : x = 10 \frac{9}{5} - 1

解

1 + x = - 10 \frac{9}{5} : x = - 10 \frac{9}{5} - 1

解为

x = 10 \frac{9}{5} - 1, x = - 10 \frac{9}{5} - 1

0 = x^{3} - 8

0 = x^{3} - 5

0 = x^{3} - 3

6 m^{2} (m + 3)^{2} = 0

solvefor x,x^4-6x^2+8=0

so l v e f or x, x^{4} - 6 x^{2} + 8 = 0
