234 = 23 x 23 x 23 x 23 = 279841
235 = 23 x 23 x 23 x 23 x 23 = 6436343
Prime factors: 2, 3, 23, 23
Others are combinations of the above, i.e.
2 x 3 = 6
2 x 23 = 46
3 x 23 = 69
2 x 3 x 23 = 138
23 x 23 = 529
2 x 23 x 23 = 1058
3 x 23 x 23 = 1587
(x^2)-23x=0
Start by factoring out an x:
(x)(x)-23x=0
x(x-23)=0
Set each quantity to 0 and solve for x:
x=0 x-23=0
x-23+23=0+23
x=23
Therefore x=0, x=23
X= -23
23 x 23 equals 529.
