1. You have the following expression: <span>(8r^-5)^-3

 2. Keepin on mind the exponents properties, you must multiply the exponent (-5) by the exponent (-3), and the exponent 1 by the exponent (-3),as below:

 </span><span>(8r^-5)^-3
 (</span>8^(1)(-3))(r^(-5)(-3<span> ))
 (8</span>^-3)(r^15)
<span>
 3. The negative exponent indicates that the base 8 must be in the denominator. Therefore, you have:

 r</span>^15/8^3
 r^15/512
<span>
 4. The simplified form of (8r^-5)^-3 is:
</span>
 r^15/512

Tems11 [23]
1st find total profit by subtracting the cost from the total revenue:

135,000 - 75,000 = $60,000 profit

Now divide the profit by the total revenue:

60,000 / 135,000 = 0.444 = 44.4% = 44% profit
