Answer:
C. 1
Step-by-step explanation:
Given:
The equation can be rewritten as:
![\displaystyle \large{\sqrt[8]{x} = 16}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7B%5Csqrt%5B8%5D%7Bx%7D%20%3D%2016%7D)
via surd property.
Since it’s an even surd, that means there only exists zero-positive numbers for value of x.
To solve this surd equation, simply clear out the surd by powering both sides by 8:
![\displaystyle \large{\left(\sqrt[8]{x}\right )^8=(16)^8}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7B%5Cleft%28%5Csqrt%5B8%5D%7Bx%7D%5Cright%20%29%5E8%3D%2816%29%5E8%7D)
Cancel the surd:
Now, evaluating 16^8 will give up a million and that’s not necessary because we are finding how many solutions this equation has. Since theee only exists one value of x, which is the solution to this equation. Therefore:
Your answer is 1 solution
The smallest degree that you can rotate a pentagon is 36 degrees
Answer:
18√7x⁶
Step-by-step explanation:
Given the expression 7√28x⁶+4√7x⁶, we are to fund the sum in its simplest form as shown;
7√28x⁶+4√7x⁶
= 7√(7*4)x⁶+4√7x⁶
= 7*2√7x⁶+4√7x⁶
= 14√7x⁶+4√7x⁶
Factor out the like term
= 2√7x⁶(7+2)
= 2√7x⁶(9)
= 18√7x⁶
Hence the sum is equivalent to 18√7x⁶
