Answer:

$\sqrt[n]{x^a}=x^{a/n}$

Step-by-step explanation:

While the "law"

$\sqrt[n]{x^n}=x$

may seem more applicable, and may seem to be a special case of the law shown in the answer above, it is not true in general. For example, ...

$\sqrt{x^2}=|x|\ne x \quad\text{for x $$

1. x = 1/ ( $\sqrt{3} - \sqrt{2)}$ = $\sqrt{3}+ \sqrt{2}$ ;
( $\sqrt{x} -1/ \sqrt{x} )^{2} = x + 1/x - 2 =$ =

Write an equation in point-slope form of the line with slope –8 that contains the point j(–3, 2).

patriot [66]

The point-slope formula is y-y1=m(x-x1). You will then substitute into this equation. The answer will be y-2=-8(x+3).

Use elimination to solve each system if equation 3x+2y=0and x-5y=17

kotykmax [81]

Answer:

$y = -3$

$x=2$

Step-by-step explanation:

$3x + 2y = 0$

$x - 5y=17$

to use the elimination you have to make one of the numbers same

so

$3(x-5y=17)$

and you would have to change the sign so that both of the 3x could cancel out.

New system of equation

$3x + 2y = 0$

$-3x+15y=-51$

$17y=-51$

$y = -3$

so we know the y value so now you could find the x value take one equation

$x - 5y=17$

$x +15=17$

$x = 2$

you could try it with both of the equations

$3x + 2y = 0$

$3x + - 6=0$

$3x-6=0$

$3x=6$

$x=6/3$

$x=2$
