x2=20 - 11
x2= 9
vì 32=9
suy ra x = 3
x3 = 40 + 24
x3= 64
vì 43=64
suy ra x=4
x2 = 20 - 11
x2 = 9
Vì 9 = 3 . 3 = > x = 3
x3 = 40 + 24
x3 = 64
Vì 64 = 4 . 4 . 4 => x = 4
x2 = 20 - 11
x2 = 9
x2 = 32
=> x = 3
x3 = 40 + 24
x3 = 64
x3 = 43
=> x = 4
x2=20-11
x2=9
=>9=32
vậy x=3
x3=40+24
x3=64
=>64=82=43
Vậy x=4
a, x2 = 20 - 11
x2 = 9
x2 = 32
Vậy x = 3
b, x3 = 40 +24
x3 =64
x3 = 43
Vậy x = 4
x2=20 - 11
x2= 9
vì 32=9
suy ra x = 3
x3 = 40 + 24
x3= 64
vì 43=64
suy ra x=4
