Answer 1

Respuesta:

a.5/4÷3/7 = 35/12

b. (-9/7)÷(-4/5) = 45/28

c. 18/25÷(-28/36) = - (18/25) x (36/28) = 162/175

d. 11/21.3/7 = 33/147

e. -3/4. 10/21 = - 30/84 = - 15/42 = - 5/14

f. (-5/3).(-2/4) = 10/12= 5/6

g. (3/5)^4 = 81/625

h.  (3/2)^4.(3/2)^3 =  (3/2)^7

i.∛(216/125) = 6/5

j. √(16/25).∛(1/8) = (4/5) x (1/2) = 4/10 =2/5

k. (4/5)^8÷(4/5)^3 = (4/5)^5
