Porfavor lo necesito para hoy y con todas las operaciones. Y xon las respuestas simplificadas

Answer 1

a)
(2/3)² - (1/2)² = 4/9 - 1/4 = 16/36 - 9/36 = 7/36
b)
(3/4 - 5/4 / 2)² = (3/4 - 5/8)² = (6/8 - 5/8)² = (1/8)² = 1/64
c)
(2/3)² + (2/3)² = 2*(2/3)² = 2*4/9 = 8/9
d)
(3 -7/2)³ + 2³ = (6/2 - 7/2)³ + 2³ = (-1/2)³ +2³ = -1/8+8 = 8 1/8

a)
(3/4 * 2/3)³ / 5/8 = (6/12)³ / 5/8 = (1/2)³ / 5/8 = (1/8) / 5/8 = 1/5
b)
(1-1/3)³ - (1+ 1/3)³ = (2/3)³ -(4/3)³ = 8/27 - 64/27 = -56/27
c)
(1-1/2)*(1-1/3)² - 2/3² = (1/2)*(2/3)² - 2/9 = (1/2)*(4/9) -2/9 = 4/18 -2/9 =4/18-4/48 = 0
d)
(1/2)⁴ - (3-7/3)³ = (1/16) - (9/3-7/3)³ = (1/16)-(2/3)³ = (1/16)-(8/27)
= (27/432) - (128/432) = -101/432
