ExtremeBDS [4]

Option B is correct after applying the property of integer exponent and simplification.

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

=\rm (x.x^{-3}.y^{\dfrac{1}{3}})^2

=\rm (x^{-2}.y^{\dfrac{1}{3}})^2\\\\=\rm (x^{-4}.y^{\dfrac{2}{3}})\\\\=\rm \dfrac{y^{\dfrac{2}{3}}}{x^{4}}\\\\

Thus, option B is correct after applying the property of integer exponent and simplification.

How to solve y in -(y+9)=10
Allisa [31]

Answer:


Step-by-step explanation:

- (y+9) = 10


Multiply through by -1 gives us


y+9 = -10


Subtract 9 from both sides


y = -19


That's your answer.


If you work it through it satisfies the equation.


That is:


- (-19 +9) = 10


-(-10) = 10


10 = 10


Boo ya!
