Answer:

x = 12

Step-by-step explanation:

10 - 3 ( x + 7 ) = 26

First Step: Distribute

- 3 to ( x + 7 )

= 10 - 3 x - 21 = 26

Second Step: Combine like terms

10 - 21

= - 11 - 3 x = 26

Third Step: Add from both sides

26 + 11

= - 3 x = 37

Fourth Step: Divide from both sides

37 / - 3

x = 12

Answer:

$\large\boxed{D.\ 2x^2y\sqrt[5]{7xy^3}}$

Step-by-step explanation:

$\sqrt[5]{224x^{11}y^8}\\\\=\sqrt[5]{(32)(7)x^{5+5+1}y^{5+3}}\\\\\text{use}\ a^na^m=a^{n+m}\\\\=\sqrt[5]{(2^5)(7)x^5x^5x^1y^5y^3}\\\\\text{use}\ \sqrt[n]{ab}=\sqrt[n]{a}\cdot\sqrt[n]{b}\\\\=\sqrt[5]{2^5}\cdot\sqrt[5]{x^5}\cdot\sqrt[5]{x^5}\cdot\sqrt[5]{y^5}\cdot\sqrt[5]{7xy^3}\\\\\text{use}\ \sqrt[n]{a^n}=a\\\\=2\cdot x\cdot x\cdot y\cdot\sqrt[5]{7xy^3}\\\\=2x^2y\sqrt[5]{7xy^3}$
