#(x^12y^28)/(16)#

1. Distribute the exponent of 4 - multiply every exponent inside the parentheses by 4.

Remember, the numbers without exponents actually have an exponent of 1.

#((4^4x^6y^7)/(8x^3))^4#

#= (4^4x^24y^28)/(8^4x^12)#

2. #8^4#, which is 4096, can be rewritten as #4^6#.

#= (4^4x^24y^28)/(4^6x^12)#

3. Use the exponent rules to simplify. When dividing powers with the same base, subtract the exponents.

#= 4^-2x^12y ^28#

This can be rewritten as

#= (x^12y^28)/(4^2)#

#= (x^12y^28)/(16)#

That's your final answer!
