Find the 5th term of the expansion of ( 6x + 6y)^11
Elodia [21]

The 5 th term of the given expression is 330(6x)^{7}( 6y)^{4}.

Step-by-step explanation:

Given,

(6x+6y)^{11}

To find the 5th term of the given expression.

Formula

In a binomial series (a+b)^{n}, the r th term is = nC(r-1) a^{n-r-1} b^{r-1}, where,

nC(r-1) = \frac{n!}{(r-1)!(n-r+1)!}

Now,

Putting, n=11, r = r, a=6x and b=6y we get,

5 th term = 11C4(6x)^{7}( 6y)^{4}

= \frac{11!}{4!7!}(6x)^{7}( 6y)^{4}

= \frac{11X10X9X8X7!}{7!X4X3X2X1}(6x)^{7}( 6y)^{4}

= 330(6x)^{7}( 6y)^{4}

Here is the answer.

How do u teach<br>long division​
zavuch27 [327]

Explanation:

To do long division, follow the method pattern "DMS down".

D for divide.

M for multiply.

S for subtract.

Down is to bring down.

Use an example:

52 ÷ 2?

Divide 2 by the first digit of 52.

  2          Whenever you divide, put the answer at the top.

2∫52

Multiply answer by number you are dividing by.

  2

2∫52

   4      When not dividing, put the work under the question.

Subtract.

   2

2∫52

   <u>4</u><u>  </u>

   1

Bring down the next digit.

   2

2∫52

   <u>4  </u>

   12

Divide into the new difference 12.

   26

2∫52

   <u>4  </u>

   12

Multiply the new digit.

   12

Subtract.

   26

2∫52

   <u>4  </u>

   12

   <u>12</u><u> </u>

    0    You stop when you get to 0. If you ran out of digits to bring down, write this as a remainder.
