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