Product roots

[Voxynn]

Hi,

I'm trying to find a list of 2 number, the product of which will make 1.
For example, 0.5 and 2, 0.125 and 8.
Is there a way for me to find the roots of 1, possibly over a given range if that's easier?

Thanks.

In A1 column write number and in A2 add how much you want to grow (for example =A1+0,1) then extend A2 down.

In B1 write =1/A1 and extend down

Or, in A1 write =RANDBETWEEN(first number, last number) and extend down and in B1 same formula =1/A1 and extend down
