Are the expressions (-2)^4 and -2^4 equivalent? explain how you know.

They are not equivalent. 
because (-2)^4 is in the parenthesis so the - before 2 are together and both will go to the 4 power so the answer will be: (-2)^4 = 16 
but the other one is not in the parenthesis so the - will not go to the 4 power and the answer will be: -2^4 = -16 
so 16 is not equivalent to -16 :)))
i hope this is helpful 
have a nice day 

Ihave, but this question is gonna probably get deleted.
