PLEASE HELP!!
Mario simplified the expression (4z^8)^-3 as shown.
(4z^8)^-3 = 4z^8 x (-3) = 4z^-24 = 4/z^24
Which statement explains Mario’s error?
He should have added the exponents instead of multiplying them.
He should have subtracted the exponents instead of multiplying them.
He should have applied the exponent –3 to 4, and not to z, to get 4^-3z^8 = 4^-3z^8 = z^8/64.
He should also have applied the exponent –3 to 4 to get 4^-3z^8 x (-3) = 4^-4 z^-24 = 1/64z^24.
