Question

dau coroana si 21 de puncte​

Answer 1

a) -12V14 : (-6V2) = 2V7

b) -2V15 : (4*3V3 - 9*2V3 + 5V3) = -2V15 : (12V3 - 18V3 + 5V3) = -2V15 : (-V3) = 2V5

c) Rationalizezi ambele fractii cu V2

[(5V2 -2*2)/(4*2) - (7V2-3*2)/(6*2)] : 5/6V14 =

[(5V2-4)/8 - (7V2 - 6)/12] : 5/6V14 amplifici prima fractie cu 3, a doua cu 2

[(15V2-12 - 14V2+12)/24] : 5/6V14 =

V2/24 * 6V14/5 =

V28/20 = 2V7/20 = V7/10
