(12x-43)=4.(84:83)
12x-64=4.8
12x-64=32
12x=32+64
12x=96
x=96/12
x=8
(12x-64).512=4.4096
(12x-64).512=16384
(12x-64) = 16384 : 512
(12x-64) = 32
12x = 32 + 64
12x = 96
x = 96 : 12
x = 8
( 12x - 43 ) . 83 = 4 . 84
( 12x - 64 ) . 512 = 16384
12x - 64 = 16384 ÷ 512
12x - 64 = 32
12x = 32 + 64
12x = 96
x = 96 ÷ 12
x = 8
( 12x - 4\(^3\)) . 8\(^3\)= 4.8\(^4\)
( 12x - 64) . 512 = 16 384
12x - 64 = 16 384 : 512
12x - 64 = 32
12x = 32 + 64
12x = 96
x = 96 : 12
x = 8
=> x = 8
\(\left(12x-4^3\right)\cdot8^3=4\cdot8^4\)
\(12x-64=4\cdot8^4\div8^3\)
\(12x-64=4\cdot8\)
\(12x-64=32\)
\(12x=64+32\)
\(12x=96\)
\(x=96\div12\)
\(x=8\)
( 12x - 4^3 ) = 4*8^4 / 8^3
12x - 64 = 4*8
12x - 64 = 32
12x = 32+64
12x= 96
x=96/12
x=8
Vậy x=8
\(\left(12x-4^3\right).8^3=4.8^4\)
\(\left(12x-64\right).512=16384\)
\(\left(12x-64\right)=16384:512\)
\(12x-64=32\)
\(12x=96\)
\(x=8\)
vậy \(x=8\)
(12x-43).83=4.84
(12x-64).512=16384
12x-64=16384:512
12x=32+64
X=96:12
X=8
Vay x=8
