Presentation leaves a lot to be desired.
Will take a GUESS at :-
[ 3 â ( a^6 (9) ) ] / ( 3 a ²)
[ 9 a³ ] / ( 3 a ²)
3 a

3â(a^6*9) / 3a^2 =
3â(a^3*a^3*3*3) / 3a^2 =
3(a^3)(3) / 3a^2
3a
3â(a^3*a^3*3*3) / 3a^2 =
3(a^3)(3) / 3a^2
3a

3â(a^6 * 9) / 3a^2
3â((3a^3)^2) / 3a^2
3*3*a^3 / 3a^2
3*(3*a^2)*a / 3a^2
3a
3â((3a^3)^2) / 3a^2
3*3*a^3 / 3a^2
3*(3*a^2)*a / 3a^2
3a

3â(a^9 * 9)/3a^2 (cancel out 3)
= â(9a^6)/3a^2
= â(3a^3 * 3a^3)3a^2
= 3a^3/3a^2
= (3/3)(a^3/a^2)
= a^(3 - 2)
= a
= â(9a^6)/3a^2
= â(3a^3 * 3a^3)3a^2
= 3a^3/3a^2
= (3/3)(a^3/a^2)
= a^(3 - 2)
= a
