Explanation:

First, we can use this rule of exponents to rewrite this expression:

#x^(color(red)(a) xx color(blue)(b)) = (x^color(red)(a))^color(blue)(b)#

#16^(3/2) = 16^(color(red)(1/2) xx color(blue)(3)) = (16^color(red)(1/2))^color(blue)(3)#

We can rewrite and simplify this as:

#(16^color(red)(1/2))^color(blue)(3) = (sqrt(16))^color(blue)(3) = 4^color(blue)(3)#

Now, we can simplify this to:
#4^color(blue)(3) = 4 xx 4 xx 4 = 16 xx 4 = 64#
