Question

It’s delta math for it

Answer 1

We know that :

`\bigstar \ \ \boxed{\mathsf{a^(-1) = (1)/(a)}}`

`\mathsf{Given \ question \ is : \frac{1}{(x^2 - 7)^{(-1)/(2)}}}`

Using the above formula, we can write it as :

`\implies \mathsf{\frac{1}{\frac{1}{(x^2 - 7)^{(1)/(2)}}}}`

`\implies \mathsf{(x^2 - 7)^{(1)/(2)}}`

`\implies \mathsf{√(x^2 - 7)}`

Answer 2

`\sqrt{x^(2)-7`

Explanation:

Negative exponents flip the fraction, fraction exponents imply a radical to the denominator's degree, so flip the fraction and take the square root of what is in parentheses
