In the right triangle ABC of the figure

Applying the Pythagoras Theorem

$AC^{2}=AB^{2}+BC^{2}$

substitute the given values

$13^{2}=c^{2}+12^{2}$

Solve for c

If n^-2 = 1/16, then n could be which of the following?

Zepler [3.9K]

Answer:

The correct choice is

$\boxed{n=4}$

Step-by-step explanation:

The given equation is

$n^{-2}=\frac{1}{16}$

We rewrite the left hand side of the equation as a power(a number to a given exponent.

$n^{-2}=\frac{1}{4^2}$

Recall that;

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

We apply this property to obtain;

$n^{-2}=4^{-2}$

Since the exponents are the same, the bases are also the same.

Therefore $n=4$
