PLEASE HELP

Answer 1

Im going to go with A

Answer 2

$\bf \sqrt{\cfrac{50x^6y^3}{9x^8}}\implies \cfrac{\sqrt{50x^6y^3}}{\sqrt{9x^8}}\qquad \begin{cases} 50=2\cdot 5\cdot 5\\ \qquad 2\cdot 5^2\\ x^6=x^{3\cdot 2}\\ \qquad (x^3)^2\\ y^3=y^{2+1}\\ \qquad y^2\cdot y^1\\ 9=3^2\\ x^8=x^{4\cdot 2}\\ \qquad (x^4)^2 \end{cases} \\\\\\ \cfrac{\sqrt{2\cdot 5^2(x^3)^2y^2y}}{\sqrt{3^2(x^4)^2}}\implies \cfrac{5x^3y\sqrt{2y}}{3x^4}$

now, if it's asking "c is the exponent of 'y' outside the root"? well, the exponent of "y" is 1

if it's asking "d is the coefficient of 'x'"?   well, the coefficient is 3
