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 $5x^2y^5z$ .

Artyom0805 [142]

Answer:

$18=y$

Step-by-step explanation:

Assuming that your equation is $1x+1+15=y$ , you would first substitute in the 2: $(1*2)+1+15=y$

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

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