Question

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

Answer 1

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

Answer 2

There are no options.

• Use Negative Power Rule:
  `x^(-a) =(1)/(x^(a) ) .`

`(1)/(b^(4) )` <------------- only expression created by this rule.

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