if you mean \[(3\div2)^{16}\]
OpenStudy (anonymous):
no 16 is in parenthesis with a little 3/2 off to the right then there is a little 2/6 to the right of that
OpenStudy (anonymous):

You just mutilpy, 3\2 with 2\6
OpenStudy (anonymous):
and then you get a notation 1\2 over 16 = 4
OpenStudy (anonymous):
if their is a notation over another notation you can mutiply with each other..
OpenStudy (anonymous):
ok, so it will be 2root4 then??
OpenStudy (anonymous):
1\2 root 4
