1.0 × 102 or 102
Yes sir! 100 = 102
Not sure about wrighting anything, but you could write it as 123*100 except that is NOT the exponential form.
It is 1.3 or 1.3*100 if you must have the exponent.
9 cubes in exponent form = 93
The standard form is 216 Exponent form is 2.16 x 102

101
-3.0 × 100
56067 = 5*104 + 6*103 + 6*101 + 7*100.
100000 = 105
