<u>Answer:</u>

The correct answer option is $\frac {a ^ 3 b^4 } {a b^2}$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to figure out which of the given answer options show the expression after the negative exponents have been eliminated:

$\frac {a^3 b^{-2}} {a b^{-4}}$

When negative exponent changes sign, then it moves from numerator to denominator or from denominator to numerator.

Answer:

She rode her bike 20 miles... I believe this may be a trick question.

Step-by-step explanation:

Let's break down this problem...

If she is going at a rate of 5 miles per hour while walking than the maximum she could have walked in 5 hours is 25 miles.

If Angela rode her bike for 20 miles, and the got off her bike and walked "<em>the rest of the way</em>" then she should have walked 50 miles. However as we already know her rate is 5 miles per hour while walking, and therefore could only have covered half that distance in 5 hours.

Is this a multiple choice question? Is there any misssing informaation?
