3^x+2-3x=216
Giúp mình với
Tìm x biết
3x+1+15x=216
6x (3x + 1)-216 (3x 1 ) = 0
Tìm/ x,y,z biet 3x/8=3y/64=3z/216 va2x^2+2y^2-z=1
1) Tìm số tự nhiên x, biết:
a) x : 12 = 37
b) 2288 : x = 16
c) 8x - 8 = 96
d) 3x : 11 = 0
e) x : 3 = x : 4
f) 2782 : 2 [ 216 - (x - 3) ] = 13
a)\(4x+3x=217\)
b)\(9x-3x=216\)
c)\(6x-3x+23=230\)
d)\(5x+3x+x=72\)
giúp mk với mn ơi😢
tim x thuoc N biet
a,3x:11=0
b,231-(x-6)=1339:13
c,x.(x-15)=0
d,(x-1).(x-20)=0
e,25:x=x (x khac 0)
f,2782:[216-(x-3) ]=13
Bai 1;Tim x,y,z
a; x/z+y+1=y/x+z+1=z/x+y-2=x+y+z
b; 3x/8=3y/64=3z/216 va 2x^2+2y^2-z^2=1
\(2^{x+1}.3^x-6^x=216\)
a) 5x + 2x = 62 - 50
b) 5x + x = 150 : 2 + 3
c) 6x + x = 511 : 59 + 31
d) 5x + 3x = 36 : 33.4 + 12
4x + 2x = 68 – 219 : 216
