    you can convert 1/2 exponent to square root \[\huge\rm [x^\frac{ 1 }{ 2 }=\sqrt{x}\]

    so (x-2)^1/2 is same as \[\sqrt{x-2} =5\] take square both sides to cancel out the square root

    \[\huge\rm (x-2)^\frac{ 1 }{ 2 }=5\] or keep the 1/2 exponent same thing now take square both sides \[\huge\rm ((x-2)^\frac{ 1 }{ 2 })^2=(5)^2\]

    remember the exponent rule \[\huge\rm x^\frac{ m }{ n }=\sqrt[n]{x^m}\] denominator of the fraction would represent index
