In order to simplify the steps we use 2^4.
we get,


4 in the power got cancelled and we get,

Alternate method:
If we use 4^2 we get,



we use 4=2^2,

In order to get answer quicker we appropiately use 2^4=16 here.
Rules in exponent:





use 4=2^2, we get

2 got cancelled in the power, we get


we get,
