According to the rules of exponents, nx/ny = nx-y. For example, 22/22 = 4/4 = 1. Subtracting the exponents gives 22-2 = 20. Therefore, 20 = 1.

Why are there usually two solutions in quadratic equations and when do they only have one solution?

If the discriminant of the quadratic equation is greater than zero then it will have two different solutions. If the discriminant is equal to zero then it will have two equal solutions. If the discriminant is less than zero then it will have no real solutions.

Can the magnitude of a vector be equal to one of its components?

Yes. A vector in two dimensions is broken into two components, a vector in three dimensions broken into three components, etc... If the value of all but one component of a vector equal zero then the magnitude of the vector is equal to the non-zero component.


What are two numbers that are equal distance from zero on a number line called?

For two numbers to be equidistant from zero, one must be the negative of the other. As one is the negative of the other, it is the additive inverse of that number. The sum of an number and its additive inverse is zero.


What is the least number of non-zero vectors that can be added to give a resultant equal to zero?

Two - if you add two vectors of equal magnitude but in opposite directions, the resultant vector is zero.
