1.5a^2=((6))/((a^2))

解答

1.5 a^{2} = \frac{( 6 )}{( a ^{2} )}

解答

a = 2, a = - 2, a = 2 i, a = - 2 i

求解步骤

1.5 a^{2} = \frac{( 6 )}{( a ^{2} )}

在两边乘以

10

15 a^{2} = \frac{60}{a ^{2}}

在两边乘以

a^{2}

15 a^{4} = 60

解

15 a^{4} = 60 : a = 2, a = - 2, a = 2 i, a = - 2 i

a = 2, a = - 2, a = 2 i, a = - 2 i

验证解

找到无定义的点（奇点）:

a = 0

将不在定义域的点与解相综合:

a = 2, a = - 2, a = 2 i, a = - 2 i

6.86= x/(x+1000)(12)

6.86 = \frac{x}{x + 1000} (12)

\frac{9}{x} = \frac{( x + 2 )}{2}

- \frac{1}{- b + 3} = \frac{b}{2}

1 - \frac{1}{x} = \frac{4}{x}

1/((x+3))(x+3)=1,x\ne-3

\frac{1}{( x + 3 )} (x + 3) = 1, x \neq = - 3
