Selected answers to common questions:     Negative exponents.     Scientific notation. Working with Negative Exponents [10/21/1995] Is multiplying by 10 to the negative 3rd power the same as dividing by 10 to the positive 3rd power? Writing 'Square Foot' [05/05/2001] Is there a symbol for "square foot"? Zero and the Commutative Property of Multiplication [04/18/2003] If we take 0x1, we get 0, and if we take 0x2, we still get 0, for it is still 0+0+0. But if we do it the other way round, why must it still be 0, if any number to the power of 0 = 1? Zero as an Exponent [6/22/1996] How do you explain zero as an exponent? The Zero Power of Two [12/10/1998] Why is 2 to the 0 power equal to 1? I don't understand how a number can be multiplied by itself zero times. Zero to a Negative Exponent [05/06/2001] Is 0^(-3) equal to 0, or is it undefined? We can't determine whether to use the 0^x = 0 rule, or to interpret it as 1/(0^3). Page: [
