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
For the same numerator, bigger denominators mean smaller fractions (if everything's positive). 2/3 is bigger than all the other ones , which are 1/2 or less.
Answer: 2/3, 1/2, 1/4, 1/5, 1/6
Answer:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point. No solution.
