Question

Could someone check my work? And explain :)

Answer 1

wrong it is the thrid one

Answer 2

it would be the third one because when you have an exponent to an exponent you multiply when you do that you get 8 to the -8 power. a negative exponent is the reciprocal and positivley so three is equal to 1/8 to the 8th or 8 times itself 8 times. Hope this helped!
