Question

Rezolvati in Q ecuatiile :
A)2 2 supra 3 + x = 4 5 supra 6 ;
B) 2 1 supra 2 - x = 1 1 supra 3
Va rog mult ,dau coroana!

Answer 1

A)22/3+x=45/6
x=45/6-22/3=
45/6-22/3(amplificam a doua fractie cu 2)=
45/6-44/6=
1/6 apartine multimii Q
S={1/6}

b)21/2-x=11/3
x=21/2-11/3=
=(preima fractie amplificam la 3 iar a doua cu 2)=
=63/6-22/6=
=41/6 apartine multimii Q
S={41/6}
