3x^5y^2

d)3x^5y/4xy=>
0,75x^4

espero ter ajudado

Answer 2

B)

9.3 = 27
X².X = X³
Y.Y² = Y³
-----------------
27X³Y²

C)

$\frac{ 15X^{6}.Y^{3}.Z }{5XYZ}$

$\frac{15}{5}= \frac{3}{1} \\ \frac{X^{6} }{X}= \frac{X^{5}}{1} \\ \frac{Y^{3}}{Y}=\frac{Y^{2}}{1} \\\frac{Z}{Z}= \frac{1}{1} \\ \frac{3. X^{5}.Y^{2}.1 }{1.1.1.1.1}=3 X^{5}Y^{2}.$
