1/2=18/36
1/3=12/36
2/9=8/36
5/18=10/36
Ответ:
1) 3
2) 33
3) 6859
Пошаговое объяснение:
1) 15-6=3^2 3^4/3^3=3
2) 17-16=1 1^8=1 2^5=32 32+1=33
3) (4^2+3)^3=(16+3)^3=361*19=6859
1) 4(х+3)+5(х-3) = 105
4х + 12 + 5х - 15 = 105
9х - 3 = 105
9х = 105+3
9х = 108
х = 108:9
х = 12
2) 3(х+20) - 4х = 10
3х + 60 - 4х = 10
- х + 60 = 10
- х = 10 - 60
- х = - 50
х = 50
3) 2х + 3(х+10) = 380
2х + 3х +30 = 380
5х + 30 = 380
5х = 380 - 30
5х = 350
х = 350 : 5
х = 70
г) 5(х+2) - 6(х-2) = 5
5х + 10 -6х +12 = 5
-х + 22 = 5
-х = 5 - 22
- х = - 17
х = 17
