because if you take number one for an example and use it for y
1^7*1^7*1^7=1 and 1^7*7*7=1
they both equal one
2.) 
![\sqrt[3]{x}\sqrt[6]{x}=\:x^{\frac{1}{3}}x^{\frac{1}{6}}=\:x^{\frac{1}{3}+\frac{1}{6}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%5Csqrt%5B6%5D%7Bx%7D%3D%5C%3Ax%5E%7B%5Cfrac%7B1%7D%7B3%7D%7Dx%5E%7B%5Cfrac%7B1%7D%7B6%7D%7D%3D%5C%3Ax%5E%7B%5Cfrac%7B1%7D%7B3%7D%2B%5Cfrac%7B1%7D%7B6%7D%7D)

join 1/3+1/6= 1/2
then you get the answer

Answer:
Step-by-step explanation:
First find factors of 81
3 81
3 27
3 9
3 3
1
81 = 3×3×3×3
81 = 3^4
Taking squareroot
∴ -√81 = -√3^4
= -3^2
= -9
