Answer:

B

Step-by-step explanation:

So we have:

\frac{x^{\frac{2}{3}}}{y^{\frac{-3}{4}}}

First, we recall that we can switch an exponent from the denominator to the numerator if we multiply the exponent by -1 and vice versa. Therefore:

=x^{\frac{2}{3}}}\cdot {y^{\frac{3}{4}}

Now, use the following property:

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

Therefore:

x^{\frac{2}{3}}=\sqrt[3]{x^2}

And:

y^{\frac{3}{4}}=\sqrt[4]{y^3}

And so together:

=x^{\frac{2}{3}}}\cdot {y^{\frac{3}{4}}\\=\sqrt[3]{x^2}\cdot\sqrt[4]{y^3}

Our answer is B :)

Which polynomial equation of least degree has -2, -2, 3, and 3 as four of its roots? (x + 2)(x - 3) = 0 (x - 2)-2(x + 3)3 = 0 (x
azamat

Answer:

(x + 2)²(x - 3)² = 0

Step-by-step explanation:

Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0

Answer:

8 interior angles

Step-by-step explanation:

  • There is a simple trick to finding the number of interior angles
  • For instance, a triangle has 3 sides, and how many angles are in a triangle? 3
  • A square has 4 sides and 4 interior angles
  • A pentagon has 5 sides and 5 interior angles
  • So an octagon, the shape we have here, has 8 sides so 8 interior angles
