Marina correctly simplified the expression (-4a^-2 b^4)/(8a^-6b^-3) assuming that a does not equal 0 and b does not equal 0. Her
Elza [17]
For this case we have the following expression:
 (-4a ^ -2 b ^ 4) / (8a ^ -6b ^ -3)
 We can rewrite the expression using properties of exponents.
 We have then:
 (-4/8) * ((a ^ (- 2 - (- 6))) (b ^ (4 - (- 3))))
 Rewriting we have:
 (-2/4) * ((a ^ (- 2 + 6)) (b ^ (4 + 3)))
 (-1/2) * ((a ^ 4) (b ^ 7))
 -1 / 2a ^ 4b ^ 7
 Answer:
 
The exponent of the variable b in Marina's solution should be 7

Could someone possibly help me with this question?
MrRa [10]

Answer:

See explanation

Step-by-step explanation:

      Statement                     Reason

1. the diagram shows segment AC with point B on this segment, then

   AB+BC=AC              <u>Segment addition postulate</u>

2. Given AB=2x,\ BC=6x+8,\ AC=32, then

   2x+6x+8=32              <u>Substitution property</u>

3. Simplify the equation as follows

   8x+8=32                      <u>Combine like terms</u>

4. Subtract 8 from both sides

   8x+8-8=32-8\\ \\8x=24          <u>Subtraction property of equality</u>

5. Divide by 8:

   x=3                                <u>Division property of equality</u>
