Remember
x^{ \frac{m}{n} }= \sqrt[n]{x^m}

so
x^{ \frac{1}{2} }= \sqrt[2]{x^1} or √x

Fractional exponents are also called radicals or rational exponents. To get rid of this type of exponents, we remember the law of exponents when we multiply them. For instance,
<span>
x^1/2
</span><span>
x^1/2 ( x^1/2 ) = x^(1/2+1/2) = x^(1) = x
</span><span>
Therefore, x^1/2, when 2 times in a multiplication gives x and so x^1/2 is the square root of x.</span><span>

The graph below shows the numbers of cups of apple juice that are mixed with different numbers of cups of lemon-lime soda to mak
Misha Larkins [42]
The ratio of the number of cups of apple juice to lemon-lime soda is 6:1.

If there is a point on the graph at (1, 6), where the x-coordinate the number of cups of lemon-lime soda and y-coordinate is the number of cups of apple juice, you can deduce the ratio (6 cups of apple juice for 1 cup of lemon-lime soda). 

As you imagine on the graph, this pattern continues, with 2 cups of lemon-lime soda for 12 cups of apple juice, that simplifies to 1 cup of lemon-lime soda for 6 cups of apple juice. Since the question asks for the ratio of apple juice to lemon-lime soda, you just reverse the values and get 6:1

What is the area , in square meters of the shaded part of the rectangle below
Licemer1 [7]

Answer:

123.5 m^2

Step-by-step explanation:

The area of the whole rectangle is 9 x 19 = 171 m^2

The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is

(height x length)/2

171 - 47.5 = 123.5 m^2
