Question

how do i write the expression 256^-3/4 in radical notation? and how do i evaluate it?

Answer 1

256 = 16*16

(16)^2 *-3/4 = (16)^-3/2

16 = 4*4


(4)^2*-3/2 = 4^-3 = 1/4^3

Answer 2

so this is written in radical notation: (16)^-3/2

and this is it evaluated? 1/4^3

Answer 3

yes

Answer 4

cool. thank you!!

Answer 5

that answer is WRONG!!!! it cannot be a negative because the rule of radical notation has to change it to a positive
