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:

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

HELP ME WITH MY MATH RIGHT NOW!!!!!!!!!!!!

ludmilkaskok [199]

The equation of a line that passes through $(x_1,y_1)$ and has a slope of m is $y-y_1=m(x-x_1)$

so given the point (3,1) and slope -2
(3,1), (x1,y1)
x1=3
y1=1
m=-2

the equation is
$y-1=-2(x-3)$

Simplify:<br> 9x² - 4x - 3= [?]<br> X=-2

Bess [88]

Answer:

Step-by-step explanation:

Given x = -2,

Substitute x into the expression. $9x^{2} -4x-3=9(-2)^{2} -4(-2)-3\\= 9(4)-4(-2)-3\\= 36+8-3\\=44-3\\=41$
