Answer:

B. $\frac{1}{x^2y^7}$

Step-by-step explanation:

Given:

$(x^3y^{-2}z)(x^{-5}y^{-5}z^{-1})$

Hence Solving the given expression we get;

By Law of Indices which states;

$(a^xb^yc^z)(a^pb^qc^r) = a^{x+p}b^{y+q}c^{z+r}$

Hence we get;

$x^{3+(-5)}y^{(-2)+(-5)}z^{1+(-1)}\\\\x^{3-5}y^{-2-5}z^{1-1}\\\\x^{-2}y^{-7}$

Also We know that

$a^{-6} =\frac{1}{a^6}$

So,

$\frac{1}{x^2y^7}$

The power of a power

The power of a power is related with the multiplication of the exponents. For example:

$(2^4)^5=2^{4x5}=2^{20}$

In this case

$(7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2}$

Then, the exponentes 1/2 and 2 are multiplied.

Since

$\frac{1}{2}\cdot2=1$

Then,

$\begin{gathered} (7^{\frac{1}{2}})^2=7^{\frac{1}{2}\cdot2} \\ =7^1=7 \end{gathered}$

Then, the answer is 7.

Answer- A. 7
