As the powers are not applied to the numbers you cane split it like this:
#(6xx2)/2 xx(x^(-4/3)xxx^(2/3))/(x^(-1/3))#
#color(blue)("For the number we have "6xx2/2" " =" " 6xx1" " =" " 6#
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The powers being negative means they go to the other side of the 'line' and in doing so changing from negative to positive.
So#" "(x^(-4/3)xxx^(2/3))/(x^(-1/3))" is the same as "(x^(1/3)xx x^(2/3))/(x^(4/3))#
#color(brown)("'~~~~~~~~~~~~~~~~~ Note ~~~~~~~~~~~~~~~~~~~~~~~")#
#color(brown)("If you have for example "a^2xxa^3" then this is the same as")#
#color(brown)(a^(2+3)". The same happens with fractional powers.")#
#color(brown)("'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")#
#" "(x^(1/3)xx x^(2/3))/(x^(4/3))" " =" " (x^(1/3+2/3))/(x^(4/3))#
#" "= (x^(3/3))/(x^(4/3))#
#color(brown)("'~~~~~~~~~~~~~~~~~ Note ~~~~~~~~~~~~~~~~~~~~~~~")#
#color(brown)("If you have for example "a^2/a^3" then this is the same as")#
#color(brown)(a^(2-3)". The same happens with fractional powers.")#
#color(brown)("'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")#
#" "= (x^(3/3))/(x^(4/3)) #
