Which expression is equivalent to √125x6^y15^z3^?
Rina8888 [55]

Answer:

5x^2y^5z

Step-by-step explanation:

Hello!

Expand the cube root:

  • \sqrt[3]{125x^6y^{15}z^3}
  • \sqrt[3]{125}* \sqrt[3]{x^6} * \sqrt[3]{y^{15}}*\sqrt[3]{z^3}

Use exponent rule:

  • \sqrt[a]{b^c} = b^{\frac ca}

<h3>Simplify</h3>
  • \sqrt[3]{125}* \sqrt[3]{x^6} * \sqrt[3]{y^{15}}*\sqrt[3]{z^3}
  • 5^{\frac33}*x^{\frac63}*y^{\frac{15}{3}}*z^{\frac33}
  • 5 * x^2 * y^5 * z
  • 5x^2y^5z

The answer is 5x^2y^5z.

Next, simplify and combine like terms: 2+16=y

Finally, simplify again to get the answer: 18=y
