Matematică, întrebare adresată de dodo35, 9 ani în urmă

Va rog ex 17 si a si b

Anexe:

renatemambouko: x/1,2=(2,5-1 5/3)²/(5/24)
x/1,2=(5/2-8/3)²/(5/24)
x/1,2=[(15-16)/6]²/(5/24)
x/1,2=[(-1)/6]²/(5/24)
x/1,2=(1/36)/(5/24)
x/1,2=1/36 *24/5
x=(2/15)*(12/10)
x=4/25
dodo35: multumesc , puteti sa ma ajutati si la punctu b ??

{128/15[1/5+x(4/3-6/5)]*5/3}/2,1(3)=16⁸/8¹⁰
{128/15*5/3[1/5+x(20/15-18/15)]}/192/90=2³²/2³⁰
[128/9 *90/192(1/5+x*2/15)]=2²
20/3*(1/5+x*2/15)=4
1/5+x*2/15=4:20/3
1/5+x*2/15=3/5
x*2/15=3/5-1/5
x*2/15=2/5
x=2/5 :2/15
x=2/5 *15/2
x=3
