When multiplying exponents, such as #x# times #x#, would the answer be #x^2# or #2x#?

Answer 1

Mila Anderson

#x^2#

Remember that the multiplicity of a value by itself is indicated by the exponent.

As an illustration:

In your case, #x^2# means that #x# is multiplied by itself #2# times, or "#x*x#".

In contrast, #2x# means #x# is multiplied by #2#. You can think of #2x# as being "#x+x#" (#x# plus #x#).

When multiplying exponents with the same base, such as x times x, the answer is x^2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
