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

A piece of paper is 11 inches long and 8.5 inches wide. What is the area of the paper in square centimeters? (Please show work!)
goldenfox [79]
If you would like to know what is the area of the paper in square centimeters, you can calculate this using the following steps:

1 inch equals to 2.54 centimeters.

11 inches = 11 * 2.54 = <span>27.94 centimeters long
8.5 inches = 8.5 * 2.54 = </span><span>21.59 centimeters wide

11 inches long * 8.5 inches wide = 27.94 centimeters long * 21.59 centimeters wide = </span>27.94 * 21.59 = 603.22 square centimeters
<span>
The correct result would be </span>603.22 square centimeters.<span>
