Answer:
4^12 y^24
Explanation:
(16y^5/4y^3)^12
Simplify inside the parentheses
(16/4 * y^5/y^3) ^ 12
When dividing the bases to the exponent, we keep the base and subtract the exponent
(4 y^(5-3)) ^12
(4 y^2) ^12
Remember (ab)^c = a^c * b^c
4^12 y^2^12
When we have a power to a power, we can multiply the exponents
a^b^c =a^(b*c)
4^12 y^(2*12)
4^12 y^24
