What is (A+B)⁵?
You do A⁵
Next you do (A+A+A+A) times B which equals A⁴B
Next you do (A+A+A) times (B+B) which equals A³B²
Next you do (A+A) times (B+B+B) which equals A²B³
Next yo do A times (B+B+B+B) which equals AB⁴
Lastily you do B⁵
Now you put the answer together
=A⁵ + A⁴B + A³B² + A²B³ + AB⁴ + B⁵
Now you put the answer together
=A⁵ + A⁴B + A³B² + A²B³ + AB⁴ + B⁵
