Which expresion is equivalent to (x1/2y-1/4)-2

love history [14]

For this case we must find an expression equivalent to:

$(x ^ {\frac {1} {2}} * y ^ {-\frac {1} {4}})^{-2}$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So:

$x ^ {\frac {1 * -2} {2}} * y ^ {-\frac {1 * -2} {4}} =\\x ^ {\frac {-2} {2}} * y ^ {\frac {2} {4}} =\\x ^ {-1} *y ^ {\frac {1} {2}}$

We have by definition of properties of powers that: $a ^ {-1} = \frac {1} {a ^ 1} = \frac {1} {a}$

Then, rewriting the expression:

$\frac{y^{\frac{1}{2}}}{x}$

Answer:

$\frac{y^{\frac{1}{2}}}{x}$

Carpet is installed in the hallways of a building. The cost of carpet and installation is $32.50 per square yard. A total length

Aloiza [94]

Answer:

$Total = \$7800$

Step-by-step explanation:

Given

$Cost = \$32.50$ per square yard

$Length = 432.0ft$

$Width = 5.0ft$

Required

Determine the cost of carpet and installation

First, calculate the area of the carpet

$Area = Length * Width$

$Area = 432.0ft * 5.0ft$

$Area = 2160ft^2$

Convert to square yard

$Area = \frac{2160yd^2}{9}$

$Area = 240yd^2$

The cost is then calculated as:

$Total= Area * Unit\ Cost$

$Total = 240 * \$32.50$

$Total = \$7800$
