Here's how you could solve this problem:
(root of 5)√x^4 multiplied by (root of 5)√x^4
- combine like terms
- you should get (root 5)√x^8 -> because, with the Laws of Exponents, multiplying like terms with exponents is seen to be equivalent to adding the exponents
- finally, write out x^(5/5) multiplied by x^(3/5)
- this is because you've taken out the largest multiple of 5 in the exponent that you had (5 is the largest multiple of 5 out of 8), and you subtracted 8 by 5 to get the remaining exponent of the other term
- simply exponents, and you're done :D :D :D :D :D

12.1 option C
Step-by-step explanation:
By using Pythagoras Theorem,
![{x}^{2} = {(11)}^{2} + {(5)}^{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20%7B%2811%29%7D%5E%7B2%7D%20%20%2B%20%20%7B%285%29%7D%5E%7B2%7D%20)
![x = \sqrt{121 + 25} = \sqrt{146}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%7B121%20%2B%2025%7D%20%20%3D%20%20%5Csqrt%7B146%7D%20)
x=12.08
x=12.1

Answer:
So the domian of square root of x will be All real numbers greater than or equal to 0.
This can be expressed as:
[0 , ∞)
or
x ≥ 0
