Step-by-step explanation:
The applicable property of exponents is ...
![\sqrt[n]{x^m}=x^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
The 4th selection uses this property directly. The 3rd selection uses the property

to show that the cubes of the two expressions are equivalent. Since all the numbers involved are real numbers, this is equivalent to showing the expressions equivalent.
Combine like terms
2a² + 6a² = 8a²
8a² - 5
The factors are (a - 2) and (6a + 5) .
If the expression is equal to zero, then 'a' can be 2, and 'a' can be -5/6 .
Wdym “these are the right answers”..?
