360=77+59+62+66+12x (angle sum of polygon)
360=264+12x
360-264=12x
96=12x
x=8

Answer:
The inverse of logarithmic function
f⁻¹(x)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given f(x) = log₂ˣ ( 2 is a radical)
<em>Let x₁ and x₂ be the ∈ domain f</em>
⇒f(x₁) = f(x₂)
⇒ ![log_{2} x_{1} = log_{2} x_{2}](https://tex.z-dn.net/?f=log_%7B2%7D%20x_%7B1%7D%20%3D%20%20log_%7B2%7D%20x_%7B2%7D)
⇒ x ₁ = x₂
<em>Therefore f(x) is one-one function</em>
Let y = f(x) = log₂ˣ
⇒ y = log₂ˣ
⇒
<em>f(x) is a one-one function and onto</em>
⇒
⇒ f⁻¹(x)
<em>The inverse of logarithmic function </em>
f⁻¹(x)
Answer:
The equation is either n-6^3 (this is without cubing the 6, this is probably what your teacher is looking for.) or n-216 (this is what the equation looks like when 6 is cubed)
