Answer:
\(5.4n^5\)
Step-by-step explanation:
Given:
Expression, \(4n^5+3.5n^5+(-2.1)n^5\)
Simplify the given polynomial.
\(\Rightarrow 4n^5+3.5n^5+(-2.1)n^5\)
Sign rule: (+)(-) = -
\(\Rightarrow 4n^5+3.5n^5-2.1n^5\)
Each term has variable n with degree 5.
Combine the coefficients of variable.
\(\Rightarrow (4+3.5-2.1)n^5\)
\(\Rightarrow 5.4n^5\)
Hence, The simplest form of polynomial is 5.4n⁵
