Question

(5/3-3/5)la puterea a2a : (8/5)la puterea a2a -- (4/3--3/4)la puterea a2a : (5 intregi si 5/6)la puterea a2a

Answer 1

25-9/15 la puterea a 2a * 5/8 la puterea a 2a - 16-9/12 la puterea a 2a : 35/6 la puterea a 2a=
16/15 la puterea a2a * 25/64-7/12 la puterea a 2a* 6/35 la puterea a 2a=
256/225*25/64-49/144*36/1225=
32/36-9/700 (simplifici) = 496/500

Answer 2

=[(25-9)/15]²:64/25-[(16-9)/12]²:(35/6)²=
(16/15)²·25/64-(7/12)²:1225/36=
256/225·25/64-49/144·36/1225= se simplifica ce se poate=
4/9-1/4·1/25=4/9-1/100=(400-9)/900=391/900=0,43(4)
