f(n)= n^2 -6n - 16

Set f(n) =0

n^2 -6n-16=0

Factor it

(n-8)(n+2)=0

Solve for n

n-8=0 n+2=0

n=8 and n =-2

High expression is equivalent to ^4 square root x^10

Talja [164]

In order to find which expression is equivalent to $\sqrt[4]{x^{10}},$ simplify all given expressions:

$\sqrt[4]{x^{10}}=x^{\frac{10}{4}}=x^{\frac{5}{2}}=x^{2.5}.$

$x^2(\sqrt[4]{x^2})=x^2\cdot x^{\frac{2}{4}}=x^2\cdot x^{\frac{1}{2}}=x^2\cdot x^{0.5}=x^{2.5}.$

$x^{2.2}.$

$x^3(\sqrt[4]{x} )=x^3\cdot x^{\frac{1}{4}}=x^3\cdot x^{0.25}=x^{3.25}.$

$x^5.$

Therefore,

Answer: correct choice is A
