Simplify (xy)^-3/(x^-5y)^3
Nesterboy [21]
Use:\\\\(a\cdot b)^n=a^n\cdot b^n\\\\a^n:a^m=a^{n-m}\\\\\left(a^n\right)^m=a^{n\cdot m}\\\\a^{-n}=\left(\frac{1}{a}\right)^{n}\\==================================\\\frac{(xy)^{-3}}{(x^{-5}y)^3}=\frac{x^{-3}y^{-3}}{(x^{-5})^3y^3}=\frac{x^{-3}y^{-3}}{x^{-15}y^3}=x^{-3-(-15)}y^{-3-3}=\boxed{x^{12}y^{-6}=\frac{x^{12}}{y^6}}

The equation 2(5+7) = (2•5) + (2•7) illustrates what property?
wel

In this question, you're trying to figure out what property is being represented.

Your answer would be the Distributive Property

This is your answer because as you can see, you are "distributing" the 2 to the variables inside the parenthesis.

When you distribute the number, you would be multiplying, in which in this case there is multiplication.

Therefore, Distributive property would be the correct answer.

Cos Ф - cos Ф.sin² Ф

sin² Ф = 1 - cos² Ф
cos Ф -  cos Ф( 1-cos² Ф) = cos Ф - cos Ф  - cos³ Ф = cos³ Ф

cos Ф - cos Ф.sin² Ф = cos³ Ф
