Question

6.) Which expression is equivalent to b^-4?

Answer 1

There are no options.

• Use Negative Power Rule: $x^{-a} =\frac{1}{x^{a} } .$

$\frac{1}{b^{4} }$   <------------- only expression created by this rule.

• This is best possible, there should be answer displayed.

Answer 2

Answer:

Step-by-step explanation:

The given expression should be typed as b^(-4), which indicates that variable b has the exponent -4.

Recall that:            

     

     1

------------- = a^(-n)

   a^n

                                        1

Therefore, b^(-4) =   --------------

                                     b^4
