√(16 - x^2) is defined only for -4 ≤ x ≤ 4, and is continuous over this domain, so

\displaystyle\lim_{x\to-4^+}\sqrt{16-x^2}=\sqrt{16-(-4)^2}=0

From the other side, the limit does not exist, because all x < -4 do not belong to the domain.

Taken together, the two-sided limit also does not exist.

Please help me on this
Gre4nikov [31]

Answer: option a.

Step-by-step explanation:

Given the expression \sqrt{8^{17}}, you need to remember:

The Product of powers property:

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

The Power of a power property:

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

And:

\sqrt[n]{a^n}=a

Therefore, as the index of the radical is 2, you can rewrite 8^{17} as:

8^{17}=8^{16}*8

Rewrite this and simplify. Then:

 =\sqrt{8^{17}}

=\sqrt{8^{16}*8}=\sqrt{8^{16}}\sqrt{8}=\sqrt{(8^{8})^2}\sqrt{8}=8^8\sqrt{8}

 

This matches with the option a.
