Answer:

10

Step-by-step explanation:

Exterior angle = sum of interior angles

115 = (4k + 5) + (6k + 10)

115 = 10k + 15

100 = 10k

k = 10

How do I simplify the 6th root of 4 divided by the 3rd root of 4?
vlabodo [156]
So remember some exponentional laws

x^{m/n} = \sqrt[n]{x^m}

 \frac{x^n}{x^m}=x^{n-m} and

x^{-n}= \frac{1}{x^{n}}
so
 
4 to the 6th root=4^(1/6)
4 to the 3rd root=4^(1/3)

so
\frac{4^{1/6}}{4^{1/3}} =4^{(1/6)-(1/3)}=4^{(1/6)-(2/6)}=4^{-1/3}
and  4^{-1/3}= \frac{1}{4^{1/3}}= \frac{1}{ \sqrt[3]{4} }

the answer is \frac{1}{ \sqrt[3]{4} }
