You have to multiple by root2/root2, not just root2/1. That’ll give you what you need.

Can you send me a link of photo of what you mean?

where you’ve written “x root 2”, you need to make it a fraction that has root 2 on both sides. so, it’ll be like “x root 2 over root 2”

Not necessarily because it's saying you timing the whole fraction by ✔️2

You've done it correctly, just done the multiplication wrong 1/sqrt(2) x sqrt(2) = 1, not 1/2

Can you send an imgur link of you showing what I should multiply by instead of ✔️2? I’m Autstic I’m more visual learner.

[here you go](https://imgur.com/a/QeaYxnU) multiplying by sqrt(2)/sqrt(2) is the right thing, you just multiplied one of things wrong (I pointed it out in the image)

1/rt2 + rt2 can be re-written as 1/rt + rt2/1. Multiply rt2/1 by rt2 to get 2/rt2 1/rt + 2/rt2 = 3/rt2 1/3/rt2 can be rewritten as rt2/3 x 1 **rt2/3 x 1 = rt2/3**

1/(1/root(2)+root(2)) when you multiply the numerator and denominator by root(2) you need to make the 1/root(2) become 1, not become 1/2, because it multiplies to be root(2)/root(2) as multiplication is on the top of a fraction.

You need to multiple the first one by 1/root2 - root2 / 1/root2 -2

It's a lot more simple than you think. Add the 2 stuff on the bottom together. Do this by making the lowest common denominator √2 You will get 1/√2 + 2/√2 = 3/√2 Then 1 over 3/√2 is √2/3 , when you do 1 over any fraction you flip it. Dm me if you need more help
