Answer:

$-7 = n$

Step-by-step explanation:

$0,002 \times 0,0004 = 0,0000008$

$0,0000008 = 8 \times {10}^{-7}$

Which expression represents the number of possible combinations of n items taken rat a time

Likurg_2 [28]

Answer:

nCr = n! / (r!)(n-r!).

Step-by-step explanation:

That would be nCr = n! / (r!)(n-r!).

A quick way of working these out is as follows:

Take 7C4:

this is 7*6*5*4/4*3*2*1 Cancelling out the 4 and 3*2:

= 7*5

= 35.

15C12 = 15C(15-12)

= 15C3

= 15*14*13 / 3*2*1

= 5*7*13

= 455.

Simplify: 3√4 508/1331

olga2289 [7]

Answer:

The simplified form of ³√{4(508/1331)} is {1(7/11)}.

Step-by-step explanation:

Given that:

³√{4(508/1331)}

Let we first convert the mixed fraction to simplest fraction form.

= ³√{(1331*4+508)/1331}

= ³√{(5324 + 508)/1331}

= ³√(5832/1331)

Comparing the fraction with x√{(a/b)}, we get

a = 5832 , b = 1331 and x = 3

Using exponent rule x√{(a/b)} = {(x√a)/(x√b)}, we get

= {(³√5832)/(³√1331)}

Let now find the prime factorization of 5832 and 1331.

Prime factorization of 1331

11 | 1331

11 | 121

11 | 11

| 1.

Prime factorization of 1331 = 11 * 11 * 11

³√(1331)

= ³√(11 * 11 * 11)

= 11

⇛³√(1331) = 11

Now,

Prime factorization of 5832

2 | 1458

3 | 729

3 | 243

3 | 81

3 | 27

3 | 9

3 | 3

| 1.

Prime factorization of 5832 = 2*2*2 * 3*3*3 * 3*3*3

Hence, ³√(5832)

= ³√(2*2*2 * 3*3*3 * 3*3*3)

= 2 * 3 * 3

= 6 * 3

= 18

⇛³√(5832) = 18

Therefore,

{(³√5832)/(³√1331)}

= 18/11

= {1(7/11)

Answer: Hence, the simplified form of ³√{4(508/1331)} is {1(7/11)}.
