Final answer:
The student's question is about simplifying an algebraic expression, for which combining like terms and applying exponent rules is crucial. Due to incomplete information in the expression, a precise solution cannot be given. General principles of simplification, cubing exponents, and solving higher-degree equations are explained instead.
Step-by-step explanation:
The question involves simplifying an algebraic expression by combining like terms and applying exponent rules.
Unfortunately, the provided expression appears incomplete or has typos, so I cannot offer a detailed solution. However, I can explain some general principles that might be useful for solving similar problems.
Combining Like Terms
To simplify an expression, start by combining like terms. For example, terms with the same variable part and exponent can be added or subtracted from each other.
Cubing and Powers of Exponentials
When you are dealing with powers or cubing of exponentials, remember that you should cube the coefficient and multiply the exponents by 3. This is a crucial step when simplifying expressions with exponents.
Quadratic and Higher-Degree Equations
For solving equations, it is important to note that while the quadratic formula works for degree two equations, higher-degree equations might require other techniques like graphing or numerical methods to find solutions.
