To simplify the expression (73^4)^5 using the power rule of exponents, we need to apply the rule of raising a power to a power.
According to the power rule of exponents, (a^m)^n equals a^(m*n).
In this case, (73^4)^5 equals 73^(4*5), which is equal to 73^20.
Therefore, the simplified expression is 73^20.
