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. When 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.
