(3^3x^2+100)/3 =0

解答

\frac{3 ^{3} x ^{2} + 100}{3} = 0

解答

x = \frac{10}{3 3} i, x = - \frac{10}{3 3} i

求解步骤

\frac{3 ^{3} x ^{2} + 100}{3} = 0

在两边乘以

3

3^{3} x^{2} + 100 = 0

将

100

到右边

3^{3} x^{2} = - 100

两边除以

27

x^{2} = - \frac{100}{27}

对于

x^{2} = f (a)

解为

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

x = - \frac{100}{27}, x = - - \frac{100}{27}

- \frac{100}{27} = \frac{10}{3 3} i

- - \frac{100}{27} = - \frac{10}{3 3} i

x = \frac{10}{3 3} i, x = - \frac{10}{3 3} i
