Answer:
Explanation:
To find the function with simplified base, we change every composite no into prime no. by factorizing them and rewriting in exponential form.
Given: function 

Here 4 is only composite no in base.
∴ the expontial form of 4 = 

putting it in given function we get,

⇒ 
 ( ∵ acc. to law of exponent,
 ( ∵ acc. to law of exponent, 
 )
 )
⇒

⇒
 ( ∵ acc. to law of exponent,
 ( ∵ acc. to law of exponent, 
 )
 )
⇒

⇒ 2×2×2×2×2×2×2
⇒ 128
