Step-by-step explanation:
Step 1: Let's simplify step-by-step.
[tex]4n^5 + 3.5n^5 - 2.1n^5[/tex]
[tex]= 4n^5 + 3.5n^5 + -2.1n^5[/tex]
Step 2: Combine Like Terms:
[tex]= 4n^5 + 3.5n^5 + -2.1n^5[/tex]
[tex]= (4n^5 + 3.5n^5 + -2.1n^5)[/tex]
[tex]= 5.4n^5[/tex]
Answer:
[tex]=5.4n^5[/tex]
Hope this helps.
