how do you simplify x^1/2 = x^-1/2?
I cancelled the x values and then cross multiplied but it gave me 1=-1 and I'm supposed to get x=1

Since X^1/2 is X/2,
and X^-1/2 is the same as 1/2X
So X/2 = 1/2X
2X^2 = 2
X^2 = 2/2
X^2 = 1
Square root of one is 1,
Therefore X = 1.
You can’t cancel out because you have to simply it first, as in the first step I did.
Hope that helps.

What. Is. That?
The proper way:
x1/2 = x-1/2
x1/2 = (x1/2)-1
√x = 1/(√x)
(√x)2 = 1
x = 1

How did u get X = X?
My way is just a longer way so they can understand it, but the 2s cancel and x^2 = 1

It's not longer, it's wrong. Revise the exponent rules.
And x2 = 1 has two solutions anyway.

Oh wait I read it wrong 😂😂, I read it as x/2 my bad, yh my way is wrong 😂😂
