✔ 最佳答案
1/(x^2) = ax^2
a = [1/(x^2)]/(x^2)
a = [1/(x^2)][1/(x^2)]
a = 1/(x^4)

1/(x^2) = ax^2
1 = ax^4
x^4 = 1/a
x = ±1/(4th root of a)

1 = a*(x^2)*(x^2) = a*x^4

x^4 = 1/a

x = (1/a)^1/4

1/(x^2) = ax^2
ax^2(x^2) = 1
ax^4/x^4 = 1/x^4
a=1/x^4

then.. if u have a given for x ...
ex.
assume that x=2

a=1/x^4
a=1/(2)^4
answer: a=1/16

1/x^2=ax^2 /x^2

1/x^4=a
