Evaluate each expression without using a calculator or changing the form of the expression.

1. $\log(1)$

What power would you raise $10$ to equal $1$?

1. $\log(10^3)$

What power would you raise $10$ to equal $10^3$?

1. $10^{\log(4)}$

$m^{\log_m(n)}=n$

1. $10^{3\log(4)}$

Combine the strategies from parts (b) and (c).
