A. (\frac{w^{-5}}{w^{-9} })^{ \frac{1}{2} } \\  ( \frac{w^{9} }{w^{5} })^{ \frac{1}{2} }   \\ (w^{9-5})^{ \frac{1}{2} }   \\ (w^{4})^{ \frac{1}{2} }  \\  \sqrt{w^{4} } \\ w^{2}
b.(m^{6})^{ \frac{-2}{3} } \\  (\frac{1}{m^{6} })^{\frac{2}{3} }  \\  \frac{ \sqrt[3]{1^{2} } }{ \sqrt[3]{m^{6} }^{2}  }  \\   \frac{ \sqrt[3]{1} }{m^{2*2} }   \\  \frac{1}{m^{4} }
Hope this helps!

<u>Problem A</u>
(\frac{w^{-5}}{w^{-9}})^{{\frac{1}{2}} = (\frac{w^{9}}{w^{5}})^{{\frac{1}{2}} = (w^{4})^{{\frac{1}{2}} = \sqrt[2]{w^{4}} = w^{2}
<u>
Problem B</u>
(m^{6})^{-\frac{2}{3}} = \frac{1}{(m^{6})^{\frac{2}{3}}} = \frac{1}{\sqrt[3]{(m^{6})^{2}}} = \frac{1}{\sqrt[3]{m^{12}}} = \frac{1}{m^{4}}

<u>Problem C</u>
(\frac{3x^{-4}y^{5}}{2x^{3}y^{-7}})^{-2} = (\frac{3y^{12}}{2x^{7}})^{-2} = \frac{(3y^{12})^{-2}}{(2x^{7})^{-2}} = \frac{(2x^{7})^{2}}{(3y^{12})^{2-}} = \frac{4x^{14}}{9y^{24}}

When converting between two measurement units, how can you tell which operation to use
Nadya [2.5K]
You need to see what you need to convert and how you need to convert it, do you need to divide to find out how many it goes in? Questions like that.

Look up the law of sines, I suggest Khan Academy. It is better if you know how to do it, it is very useful.

Which formula is easier to use. Finding the area of a trapezoid or circle? Explain in detail with a minimum of 4 sentence
Scrat [10]

Answer: Circle, in my opinion

Step-by-step explanation:

Trapezoid Formula: (a+b/2)h

Circle Formula: πr*2

Solving a circle requires less steps than solving for a trapezoid would, so in my opinion, finding the area of a circle is easier than a trapezoid.

Hope this helps!
