((∣x−3∣^(x+1) ))^(1/(4  ))  = ((∣x−3∣^(x−2) ))^(1/(3  ))
x3x+14=x3x23

∣x−3∣^((x+1)/4) =∣x−3∣^((x−2)/3)   ((x+1)/4)=((x−2)/3)  4x−8=3x+3  x=11
x3x+14=∣x3x23x+14=x234x8=3x+3x=11

But x=3 satisfies the given eqn.  ^4 (√(∣x−3∣^(x+1) ))=^3 (√(∣x−3∣^(x−2) ))  ^4 (√(∣3−3∣^(3+1) ))=^3 (√(∣3−3∣^(3−2) ))  ^4 (√0^4 )=^3 (√0^1 )  ^4 (√0)=^3 (√0)      0=0
