Answer:
(a) [tex]p^{10}[/tex]
In this question, you can simply just multiply the exponent of 2 and the exponent of 5, in order to get a power of 10.
(b) [tex]2x^{4}y^{2}[/tex] For this question, we need to organize the numbers as a fraction
[tex]\frac{12x^{7}y^{3} }{6x^{3 } y^{} }[/tex]
We need to subtract the exponents from each variable. In [tex]y^{3}[/tex] and y, we need to subtract 3-1 to get [tex]y^{2}[/tex]. In [tex]x^{7}[/tex] and [tex]x^{3}[/tex], we need to subtract 7-3 to get [tex]x^{4}[/tex]. Now, we can divide 12 and 6 normally to get 2. So, the answer would be [tex]2x^{4}y^{2}[/tex].
