4,2+1,3×6; 7/5-0, (4):2; 3 antregi1/4-4-(0,5)laputerea2;3/2+5:{13/5+0, (3)};4 (2,7-1,38)la puterea 2 va rog!

Answer 1

4,2+1,3•6= 4,2+7,8= 12
7/5-0,(4)= 7/5-4/9= 63-20/45= 43/45
3 întregi 1/4-4-0,(5) la puterea 2= 3/4-4•25/81= 3/4-100/81 = -157/324
3/2+5:{13/5+0(3)}= 3/2+5:44/15= 3/2+5•15/44= 3/2+75/44= 141/44
4(2,7-1,38) la puterea 2= 4•1,32 la puterea 2= 4•(33/25) la puterea 2= 4•1089/625= 4356/625
