Answer 1

(3^4 * 27^2)/9^3 = (3^4 * 3^2 * 9^2)/(3^3)^3 = (3^6 * 9^2)/3^6 = (3^6 * (3^2)^2)/ 3^6 (3^6 * 3^4)/3^6 = 3^10/3^6 = 3^4

2^-3 + (1,58)^0 - (2/5)^-1 = (1/2)^3 + (-5/2) = 1/(2^3) - 5/2 = 1/16 - 5/2 = 1/16 - 40/16 = - 39/16

(2^2 * 8^3)/4^3 = (2^2 * 2^3 * 4^3)/4^3 = 2^2 * 2^3 = 2^5

(3/4)^1 - (2,76)^0 + 3^-2 = (4/3) + 1/(3^2) = 4/3 + 1/9 = 12/9 + 1/9 = 13/9 = 1 4/9
