What is the simplified form of the following expression? Assume y=0 ^3 sqrt 12x^2/16y
pochemuha

For this case we must simplify the following expression:

\sqrt [3] {\frac {12x ^ 2} {16y}}

We rewrite the expression as:

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

We multiply the numerator and denominator by:

(\sqrt[3]{4y})^2:\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{\sqrt[3]{4y}*(\sqrt[3]{4y})^2}=

We use the rule of powera ^ n * a ^ m = a ^ {n + m} in the denominator:

\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{(\sqrt[3]{4y})^3}=\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{4y})^2}{4y}=

Move the exponent within the radical:

\frac{\sqrt[3]{3x^2}*(\sqrt[3]{16y^2}}{4y}=\\\frac{\sqrt[3]{3x^2}*(\sqrt[3]{2^3*(2y^2)}}{4y}=

\frac{2\sqrt[3]{3x^2}*(\sqrt[3]{(2y^2)}}{4y}=\\\frac{2\sqrt[3]{6x^2*y^2}}{4y}=

\frac{\sqrt[3]{6x^2*y^2}}{2y}

Answer:

\frac{\sqrt[3]{6x^2*y^2}}{2y}

Alinara [238K]
<h2><u>A</u><u> </u><u>N</u><u> </u><u>S</u><u> </u><u>W</u><u> </u><u>E</u><u> </u><u>R</u><u> </u><u>:</u></h2>

  • Perimeter of rectangle = 40 inches
  • Length of rectangle = 15 inches

Let the required Breadth of rectangle be 'x' inches

Perimeter of rectangle is calculated by the given below formula :

  • Perimeter = 2(Length + Breadth)

Now, substitute the given values in above formula :

→ 40 = 2(15 + x)

Find the value of x and y.
spayn [35]

By the geometric mean theorem,

\frac{y}{4}=\frac{12}{y} \\ \\ y^{2}=48 \\ \\ \boxed{y=4\sqrt{3}}

So, by the Pythagorean theorem,

12^{2}+(4\sqrt{3})^{2}=x^{2}\\\\144+48=x^{2}\\\\192=x^{2}\\\\\boxed{x=8\sqrt{3}}

What is the distance between the following points?
Paul [167]

Answer: You can use the formula  d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} (SEE EXPLANATION)

Step-by-step explanation:

Since the points are not written correctly, I will give you a general explanation about the procedure you should follow in order to find the distance between the two points.

By definition, the distance between two points can be calculated with the following formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

As you can observe, if you have two points:

 (x_1,y_1)\\\\(x_2,y_2)

The steps you must follow in order to solve the exercise, are the shown below:

Step 1. You can substitute the values of x_1,y_1,x_2 and y_2 into the formula d=\sqrt{(x_2-x_1)^2+(y_2-y_1)}.

Step 2. You must evaluate in order to find the distance between those two points.
