Select the correct answer.<br> Rewrite the following expression.
kolezko [41]

The <em>algebraic</em> expression x^{10/3} is equivalent to the <em>algebraic</em> expression x^{3}\cdot \sqrt[3]{x}. Thus, the right choice is option D.

<h3>How to apply power and root properties to rewrite a given expression</h3>

In this question we must apply the following set of <em>algebraic</em> properties to simplify a given expression:

x^{m/n} = \sqrt[n]{x^{m}} = \left(\sqrt[n]{x}\right)^{m}   (1)

x^{m+n} = x^{m}\cdot x^{n}   (2)

x^{m\cdot n} = \left(x^{m}\right)^{n} = \left(x^{n}\right)^{m}   (3)

Where:

  • <em>m</em>, <em>n</em> - Exponents
  • <em>x</em> - Base

And also by apply the definition of power.

If we know that the given expression is x^{10/3}, then the equivalent expression is:

x^{10/3} = \sqrt[3]{x^{10}} = \sqrt[3]{x^{9}\cdot x} = \sqrt[3]{x^{9}}\cdot \sqrt[3]{x} = x^{3}\cdot \sqrt[3]{x}

The <em>algebraic</em> expression x^{10/3} is equivalent to the <em>algebraic</em> expression x^{3}\cdot \sqrt[3]{x}. Thus, the right choice is option D.

(Confused!!!!!) What is the arc measure of a sector with area 38.485 ft2 and radius 7?
mylen [45]

Area of circle= 153.93804

(38.485/153.93804)*360=90.00114592

so about 90 degrees or 10.99557429

Hope this helps and feel free to leave a rate, thanks and brainliest (it would really help me get to virtuoso I would appreciate it a lot) ;)

Subtract 43 from 180 as the sum of a triangle adds up to 180 degrees.

180 - 43 = 137
