Answer 2

Solution:

The simplified form is $5.4n^5$.

Explanation:

Given expression to simplify:

$4n^5+3.5n^5+(-2.1n^5)$

In order to simplify the above equation we will use PEDMAS

PEDMAS stands for Parenthesis, Exponents, Divisions, Multiplications, Additions and Subtractions.

For first of we will simplify the parenthesis. On eliminating the parenthesis we will get

$4n^5+3.5n^5-2.1n^5$

Since all are like terms, we add the first two term.

$7.5n^5-2.1n^5$

Now we will subtract

$5.4n^5$
