Rewrite in simplest radical form 1/x^-3/6

VladimirAG [237]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad

\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}
\\\quad \\
% rational negative exponent
a^{-\frac{{ n}}{{ m}}} =
 \cfrac{1}{a^{\frac{{ n}}{{ m}}}} \implies \cfrac{1}{\sqrt[{ m}]{a^{ n}}}
\\ \quad \\ \quad \\

% radical denominator
\cfrac{1}{\sqrt[{ m}]{a^{ n}}}= \cfrac{1}{a^{\frac{{ n}}{{ m}}}}\implies a^{-\frac{{ n}}{{ m}}}\qquad thus\\

\cfrac{1}{x^{-\frac{3}{6}}}\implies \cfrac{1}{x^{-\frac{1}{2}}}\implies \cfrac{1}{\frac{1}{x\frac{1}{2}}}\implies \cfrac{1}{1}\cdot \cfrac{x^{\frac{1}{2}}}{1}
\\ \quad \\
x^{\frac{1}{2}}\implies \sqrt{x}$

I need help, quick, it's Algebra but super easy, thank you.

horsena [70]

16 - 2(2w + 1) = 8w - 2(8+w)
16 - 4w - 2 = 8w - 16 - 2w
- 4w + 14 = 6w - 16
14 = 10w - 16
30 = 10w
/10 /10
3 = w

I think so lol

Bill is trying to plan a meal to meet specific nutritional goals. He wants to prepare a meal containing rice, tofu, and peanuts

Novay_Z [31]

Answer:

11.33 cups

Step-by-step explanation:

240 grams of carbohydrates: x

40 x + 4 x + 26 x = 240

X = 240/70

X = 3 3/7 cups

332 grams of fats = y

0y + 13y + 70y = 332

Y = 332/83

Y = 4 cups

207 grams of proteins = z

5z + 21z + 27z = 207

Z = 207/53

Z = 3 48/53 cups

3 3/7 + 4 + 3 48/53 = 11.33 cups

Please help meee, this is my homework . (Geometry) ... I’ll rate brainliest

Rama09 [41]

1. Volume of the sphere

$V = \frac 4 3 \pi r^3 = \frac 4 3 \pi ( 8^ 3) = \dfrac{2048 \pi}{3} \approx 
2144.66$

Choice c

2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.

(x+1) + (x-3)=90

2x -2 = 90

2x = 92

x = 46

Angles x+1=47 and x-3=43

Choice b

3. midpoint A=-5, E=5

The midpoint is just the average of A and E, here zero, point D

choice b

4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:

$\dfrac{24}{x} = \dfrac{36}{12} =3$

$x = \dfrac{24}{3} = 8$

Choice a

Which expression is undefined?

slavikrds [6]

Answer: C

Work: So, after you simplify that equation, it's 8/0. You Cannot divide zero like that. You can divide 0/8, but you can't with 8/0. I hope this wasn't to confusing, and <em>Happy Holidays! :)</em>
