#p = 2#

First, square both sides so you get rid of that annoying square root symbol:

#p-1 = 1#

Now, simply add both sides by #1# to get rid of that #-1#:

#p = 2#

#p=2#

To undo the square root on the left side you have to square both sides:

#(sqrt(p-1))^2=(1)^2#

#p-1=1#

Add 1 to both sides:

#p=2#
