To simplify the expression \(7a - 5b^3\), we first need to confirm that there are no like terms that can be combined.
In the given expression, \(7a\) and \(-5b^3\) are not like terms because \(7a\) involves the variable \(a\) and \(-5b^3\) involves the variable \(b\) raised to the power of 3. They cannot be combined further.
Thus, the expression \(7a - 5b^3\) is already in its simplest form.
So, the simplified expression is:
\[ 7a - 5b^3 \]
12.
Simplify the expression.
