Answer:

D. \sqrt{250}

Step-by-step explanation:

First, use prime factorization of 250 to get \sqrt{2*5^3}

Then apply the exponent rule, a^{b+c} =a^{b}*a^{c}

=\sqrt{2*5^2*5} }

Apply radical rule: \sqrt{ab}= \sqrt{a}  \sqrt{b}, a\geq 0, b\geq 0

=\sqrt{5^{2}}  \sqrt{2*5}

Apply radical rule: \sqrt{a^{2}} =a, a\geq 0

=5\sqrt{2*5}

=5\sqrt{10}

Answer:

c. 2a^3x^4-3a^3x^3+a^4x^2

d. 63x^5y^3-30x^2y^4-7x^3y^2

Step-by-step explanation:

For this exercise you need to remember the following:

 1. The multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

2. The Product of powers property, which states that:

(a^m)(a^n)=a^{(m+n)}

3. The Distributive property:

a(b\±c)=ab\±ac

Knowing that, you can solve the multiplication of the polynomials:

c. (-2ax^2+3ax-a^2)(-a^2x^2)=\\\\=(-2ax^2)(-a^2x^2)+(3ax)(-a^2x^2)+(-a^2)(-a^2x^2)=2a^3x^4-3a^3x^3+a^4x^2

d. (6.3x^3y-3y^2-0.7x)(10x^2y^2)=\\\\=(6.3x^3y)(10x^2y^2)+(-3y^2)(10x^2y^2)+(-0.7x)(10x^2y^2)=63x^5y^3-30x^2y^4-7x^3y^2
