If the numbers $cube root of 9 space comma space fourth root of 20 space comma space space root index 6 of 25$ are arranged in ascending order, then the right arrangement is:

$root index 6 of 25 space less than space fourth root of 20 space less than space cube root of 9$

$cube root of 9 space less than space fourth root of 20 space less than space root index 6 of 25$

$fourth root of 20 space less than space root index 6 of 25 space less than space cube root of 9$

$root index 6 of 25 space less than space cube root of 9 space less than space fourth root of 20$

$root index 6 of 25 space less than space cube root of 9 space less than space fourth root of 20$

$left parenthesis 9 right parenthesis to the power of 1 third end exponent space comma space left parenthesis 20 right parenthesis to the power of 1 fourth end exponent comma space space left parenthesis 25 right parenthesis to the power of 1 over 6 end exponent$
L.C.M. of 3, 4 and 6 = 12
Now,
$rightwards double arrow space space space left parenthesis 9 right parenthesis to the power of 12 over 3 end exponent space comma space left parenthesis 20 right parenthesis to the power of 12 over 4 end exponent comma space space left parenthesis 25 right parenthesis to the power of 12 over 6 end exponent rightwards double arrow space space space left parenthesis 9 right parenthesis to the power of 4 comma space space left parenthesis 20 right parenthesis cubed comma space left parenthesis 25 right parenthesis squared$
Thus, we can say:
$root index 6 of 25 space less than space cube root of 9 space less than space fourth root of 20$
