Thank you how did you get 1/2 though sorry imconfused
n is equivalent to n^1 as you just don't need to put the one and the square root symbol is equivalent to ^2√

i.e. 1 = a and b = 2. Hopefully you can see how this works. If not let me know and I am happy to help!

27=3^3, so sqrt 27 will be sqrt 3^3 and from indices laws you know that=3^(3/2). Using another indices law, you know that 3^1 x 3^(3/2) = 3^(1+3/2) = 3^(5/2)

Is that copied from somewhere? Because there's no such word as "indice" :smile: "Indices" is the plural of "index".
