Question

What does C represent in this equation 9c^9+25=-92 what does c equal

Answer 1

c=-1.3298

Explanation:

Given the equation:

`9c^9+25=-92`

We want to solve for c.

First, subtract 25 from both sides of the equation:

`\begin{gathered} 9c^9+25-25=-92-25 \\ 9c^9=-117 \end{gathered}`

Next, divide both sides by 9.

`\begin{gathered} (9c^9)/(9)=-(117)/(9) \\ c^9=-13 \end{gathered}`

Take the 9th root of both sides:

`\begin{gathered} \sqrt[9]{c^9}=\sqrt[9]{-13} \\ c=\sqrt[9]{-13} \\ \implies c=-\sqrt[9]{13} \\ \implies c\approx-1.3298 \end{gathered}`

The value of c is approximately equal to -1.3298.
