This instructor in this video, Sal Khan, continues with 2 more exponent rules with an introduction to composite problems. Mr. Khan uses computer software (with different colors) to model several examples of how to apply rules of exponents. (07:43)

This instructor in this video, Sal Khan, continues with fractional exponents. Mr. Khan uses computer software (with different colors) to demonstrate how to solve Level 3 exponents. Several examples are modeled using a step by step approach. (09:13)

Video uses an computer software and with different colors for emphasis. Uses basic exponent knowledge, but exponents are negative. Remember exponents are not multiplication, for example 2 to the -3 power is equal to one-half to the third power. Wh...en there is a negative exponent you take the inverse of the base number. Then to solve it you would take one-half times one-half times one-half which is equal to one-eighth. Examples using fractions to negative exponents are also done. Then other examples are done. This video is for middle school students. (06:26)[more]

Instruction on why a^-b = 1/(a^b)... (and why a^0 =1).This instructor in this video, Sal Khan, continues with negative exponents. Mr. Khan uses computer software (with different colors) to illustrate his points. (04:38)
