The correct option is D 100
In 102 (10 to the 2nd power or 10 squared),
∙Base=10
∙Exponent=2
In the number form of 102,
number of zeros after 1= exponent =2
∴102=100–––––––––––
In other way, 102 is 10 multiplied 2 times, i.e., 102=10×10=100.
------------------------------
In 103 (10 to the 3rd power or 10 cubed),
∙Base=10
∙Exponent=3
In the number form of 103,
number of zeros after 1= exponent =3
∴103=1,000–––––––––––––
In other way, 103 is 10 multiplied 3 times, i.e., 103=10×10×10=1,000.
