(4^-1/2^-2)^2
= 4^(-1*2) / 2^(-2*2)
= 4^-2 / 2^-4
= 2^4 / 4^2
= 16 / 16
= 1
25 - 6r = 25
-6r = 25-25
-6r = 0
r = 0/-6
r = 0

Answer:
Quadratic Equations
A quadratic equation is one of the form ax2 + bx + c = 0, where a, b, and c are numbers, and a is not equal to 0.
Factoring
This approach to solving equations is based on the fact that if the product of two quantities is zero, then at least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both. For more on factoring polynomials, see the review section P.3 (p.26) of the text.
Example 1.
2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4.
