(8^3 x 2)^4/((1/4^-1)^2 x 2)^3 = ((2^3)^3 x2)^4/((1/4^-1)^2 x2)^3 =(2^(3x3) x2)^4/((1/4^-1)^2 x2) = (2^(9+1))^4/((1/4^-1)^2 x2)
= (2^10)^4/((1/(1/4))^2 x2) = (2^10)^4/((4)^2 x2) = (2^10)^4/((2^2)^2 x2) = (2^10)^4/(2^(2x2) x2) = (2^10)^4/(2^4 x2)
= (2^10)^4/(2^5) = (2^10)^(2^2)/(2^5) = (2^10)^2^(2-5) = (2^10)^2^(-3) = (2^10)^(1/2^3) = (2^10)^(1/8)
= 2^(10/8) = 2^(5/4) = 2^(1+1/4) = 2x(2^1/4) =
