43-2(x+3)^4=11

解答

43 - 2 (x + 3)^{4} = 11

解答

x = - 1, x = - 5

求解步骤

43 - 2 (x + 3)^{4} = 11

将

43

到右边

- 2 (x + 3)^{4} = - 32

两边除以

- 2

(x + 3)^{4} = 16

对于

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

，n 为偶数，解为

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

解

x + 3 = 416 : x = - 1

解

x + 3 = - 416 : x = - 5

解为

x = - 1, x = - 5

(x + 11)^{4} = 169

2x^4-13x^3+28x^2=23x-6

2 x^{4} - 13 x^{3} + 28 x^{2} = 23 x - 6

solvefor x,log_{10}(y)=-x^3

so l v e f or x, lo g_{10} (y) = - x^{3}

-a^3+3a^2-3a+1=0

- a^{3} + 3 a^{2} - 3 a + 1 = 0

(x - 2)^{4} = 0
