Answer 1

Answer:    $\frac{1}{x^n}$

Step-by-step explanation:

Answer 2

$\huge \red{ \boxed{ \bf \blue{ \frac{1}{ {x}^{n}}}} }$

Step-by-step explanation:

$\bf to \: find \: the \: value \: of \: ({ {x}^{ - n} })$

Note :-

Any number have the power (exponent) as a negative number, then the value of number will be reciprocal of number with same exponent but positive.

Here,

$\bf {x}^{ - n}$

We know that, reciprocal of 'x' will be 1/x.

So,

$\bf \green{ {x}^{ - n} } = \bf \purple{ \frac{1}{ {x}^{n} } }$

It's the answer.

MORE TO KNOW :-

$\bf{x}^{m} \times {x}^{n} = {x}^{m + n} \\ \bf {x}^{m} \div {x}^{n} = {x}^{m - n} \\ \bf( {x}^{m} {)}^{n} = {x}^{m \times n} \\ \\ \bf{x}^{m} = {y}^{m } \\ = > \bf x = y : x \& y \neq0,1$
