Let us arrange in ascending order.

In this type of problems we try to make the powers same by taking LCM of them.

Here, are in the powers .

So, we take LCM of 2, 4 and 3.

4= 22

2= 21

3= 31

LCM= 23 = 6

Now,

Here, all the numbers are having same power.

So, in ascending order we have

Hence, .
