If im changing the subject of an equation to make x the subject with
x^2=n
what do i do to the side n when i take ^2 away. do i square it or take the square root?. Does this apply to any power, ie would it be the same if
x^(2/1)=n or x^(3+6)=n
Yes, the correct approach for this category of equations is to raise power on each side of the equation to reduce the power of the variable to 1 (one).
This is due to the exponent relaionship:
(a^k)^(1/k) = a^1 = a
For example,
x^(7) = n
(x^(7))^(1/7) = n^(1/7)
x = n^(1/7)
