Answer: The expression (p^20)(p^-4)^2 is equivalent to p^n, where n is the power of p in the simplified expression.
To simplify the expression, we need to use the rule of exponents which states that when multiplying two powers of the same base, we can add their exponents.
So, (p^20)(p^-4)^2 = p^20 * (p^(-4))^2 = p^20 * p^(-8) = p^(20+(-8)) = p^12
So the value of n is 12.
