Oh...it's a V?
I thought it was a root sign.
Anyway, if it was meant to be a root sign, then the answer would be 1/144 because there are no brackets.
If there were brackets - sqrt(1/144) - then the answer would be 1/12.
Oops, sorry. On my computer screen, it came out as ^ for some reason. I had to reload the page a couple of times.
