yes
N = x4 x8 = x4+4 = (x4)2 = N2
9 x 4 = 36
If there is a remainder then it's not a factor otherwise yes
It's not, 4x4=16.
7
if 4 * 7 = x * 4, then x = (4 * 7) / 4 = 7
yes
Not necessarily.
N = x4 x8 = x4+4 = (x4)2 = N2
30 times 4 equals 120
9 x 4 = 36
If there is a remainder then it's not a factor otherwise yes
It's not, 4x4=16.
if c = x2 then cx2 = x4
If: x4 = 5 Then: x = 1.4953487812
