expand 2pin*(4n+1)

Solution

expand

2 πn \cdot (4 n + 1)

Solution

8 π n^{2} + 2 πn

Solution steps

2 πn (4 n + 1)

Apply the distributive law:

a (b + c) = ab + a c

a = 2 πn, b = 4 n, c = 1

= 2 πn \cdot 4 n + 2 πn \cdot 1

= 2 \cdot 4 πnn + 2 \cdot 1 πn

Simplify

2 \cdot 4 πnn + 2 \cdot 1 πn : 8 π n^{2} + 2 πn

= 8 π n^{2} + 2 πn
