Question

Simplify 4n 5 + 3.5n 5 + (-2.1n 5).

Answer 1

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

Answer 2

4n 5 + 3.5n 5 - 2.1n 5 = n 5 (4 + 3.5 - 2.1) = n 5 * 5.4 = 5.4n 5
