Answer 3

so that is the answer 4*1=4

Answer 4

yup it follows the rules of order of operations, simply everything in the parenthesis first, then simply everything affected by the exponents. the 4 isn't affected by the exponent so it remains untouched out front, while everything inside gets turned into a 1 from the 0 exponent.
