One way is to just expand it by using binomial theorem
or to use pascal's triangle
ok so
to find the nth term of a binomial, (a-b). where the binomial is to the r power you do
n-1=k
rCk times
and rCk=
so
4th term
4-1=3
6 is exponent

Answer: Tunnel tent.
Step-by-step explanation:
The tent which has the minimum area requires less nylon to manufacture,
Since, the area of Pup tent = Area of 3 square each having side 8 ft + Area of 2 equilateral triangle having side 8 ft
=
=
=
=
Now, the area of tunnel tent = Area of square having side 8 ft + total Area of half cylinder having radius 4 ft and height 8 ft
=
=
=
=
Since, 214.72 < 247.43
Thus, Tunnel tent requires less nylon to manufacture.
Answer:
Given that:
and
if a , a+ commutator, it obeys
First find:
=
Now;
=
therefore, which implies the operators a and a+ are commutators.
